Raychem Cold Shrink Termination (CST)

Raychem CST - Cold Shrink Termination

     Why is the Raychem CST better than some of the other competitive options in the marketplace? 

One advantage is that it has a large misplacement range. Typically, when a termination is misplaced, it is towards the lug end. We created our stress cone with a very large Faraday cage region to account for this. The customer has well over 1” of area they can land the semi-con cutback of the cable and still have effective stress control. We don’t advocate for sloppy workmanship but we do want to try and give the installers as much help as we can.

In addition, we developed a new EZ-Pull holdout which not only has a much lower overall pull force, but is very consistent in the force. This prevents the “jerking” that can happen with other holdouts. It is hard to put how much better the holdout feels into words since it is a very “touch” related thing. Installers are raving about this improved feature.

Other advantages: 

• Our CST uses a geometric stress control with void-filling mastic rather than a different option
• The CST indoor term also has mini-sheds that improve creepage distance, but still allow for installation in tight-fitting areas.  
• Lower cost than the alternatives in the market.

     TE Connectivity's Raychem CST cold shrink terminations are the one piece solution for high performance in cold applied terminations for polymeric cables up to 28kV.  CST offers a reliable, fast and easy to install system to ensure trouble free service.  All components are pre-expanded  on an easy to remove spiral hold out allowing installation in compact environments on prepared cable.

     The silicone body is specially formulated for excellent tracking and erosion resistance.  The extra long stress cone aids in correct positioning and integrated void-filling mastic eliminates the need for silicon grease.  Sealing mastic for the lug end is built into the expanded termination eliminating the need for additional sealing tapes.  Shearbolt and compression style terminals and pin connectors are available to provide reliable connection to a variety of conductors. 

     CST components have full trace ability to raw materials and are in compliance with the following international standards:  IEEE-48, CENELEC HD 629.1.S2 (includes IEC, BS, VDE and other international specifications).

BBIT / BPTM

Busbar Insulation Tubing

     Here we are looking at two different products.  One is BBIT - Bus Bar Insulation Tubing.  The other is BPTM which is a medium wall tubing with a slightly lower voltage rating. 

     BBIT is a heavy wall tubing for use on straight or bent bars where maximum clearance reduction...or 35 kV insulation is required.

     BPTM is a medium wall tubing for use on straight or bent bars where some clearance reduction or 25kV insulation is required.  These heat shrinkable tubes for straight and bent busbars are extremely flexible, allowing them to be easily positioned on busbars and quickly installed using a gas torch or oven.  They have a high expansion ratio, so each size of tubing fits a range of busbar sizes.  Both BBIT and BPTM tubing are ideal for original equipment assembly and for retrofit applications where access to one end is available. 

    Both BBIT and BPTM tubings are also ideal for protection against accidental bridging caused by birds and animals. 

    BBIT:  5-35kV
    BPTM: 5-25kV

Installation is as simple as this:

 

MBSM Shrink Sleeve

MBSM Wrap Around Jacket Repair (to 35kV)

     MBSM repair sleeves (heat shrinkable) protect cables in mechanically abusive environments.  They also rejacket premolded splices.  MBSM also repairs and rejackets LC shielded and moisture impervious cables.  MBSM is also used to provide strain relief to cables.

     MBSM is available in five different sizes; all supplied with a 5:1 shrink ratio (that is a high, high shrink ratio).   It is designed to be used on standard poly or elastomeric insulated / jacketed cables which may include aluminum or steel armoring.  MBSM provides a moisture vapor transmission barrier for repairing and rejacketing LC shield and moisture impervious cables.  MBSM sleeves do not provide electrical insulation.

MBSM 43/8-1200
MBSM 75/15-1200
MBSM 125/30-1200
MBSM 160/42-1200
MBSM 200/50-1200

The first letters (MBSM) are simply the material type
The first numbers (43, 75, 125, 160, 200) are all the supplied ID of the tube
The second numbers (8, 15, 30, 42, 50) are all the fully recovered OD of the tubes (fully shrunk)
The last numbers (1200) is the length of the tube in millimeters (or 4 feet long).

CRSM-CT

CRSM Cable Tap Splices

An installed CRSM-CT sleeve

     Raychem's CRSM-CT is a wrap around, sealed cable tap splice.  Utilizing a rail and channel closure mechanism, CRSM is able to stay together in the shape of a tube during the shrink process while still holding onto its high expansion full recovery.

     Designed to be used on 1000 volt and lower cables, CRSM can cover a multitude of different cable sizes, removing the need to stock multiple supplied and recovered dimension products.

CRSM-CT is available in the following sizes:

CRSM-CT 34/10-150

CRSM-CT 53/13-200

CRSM-CT 84/20-250

CRSM-CT 53/13-200

RVS Roll On Splice Seal

Rayvolve Cold Applied Splice Seal

     Rayvolve RVS Splice cover kits are the easy roll on way to insulate and seal cable connections up to 1000 volts.  The gripping force of the specially formulated EPDM elastomer combines with the high performance sealant to form a water resistant, insulating sleeve that is UL listed and CSA certified for direct burial application over in line compression connectors.

     Rayvolve splice cover sleeves feature a dual wall design with an entrapped lubricant, making installation fast and simple.  The elastomeric sleeve rolls onto the cable with minimal effort, even at temperatures below -15F. 
 
     The cable can be energized immediately.  It is ideal for use where gas and electric heating devices are not approved or allowed due to safety concerns.

     RVS-11 for #8 - 2/0

     RVS-12 for 1/0 to 250

     RVS-13 for 250-600

     RVS-14 for 600-1000

GelWrap

GelWrap Wrap Around Splice Closure (1000V)

     Gel wrap splice closures (manufactured by Tyco Electronics; formerly manufactured by Raychem) quickly and conveniently insulate and seal buried electrical connections rated up to 1000 volts.  The robust and compact design is engineered to handle the harsh environments of direct burial and manhole applications.  Gel wrap splice closures are equally well suited for insulation and jacket repair.

     Installers will appreciate the simple wrap around design and dependable gel sealing performance.  Simply wrap and snap the closure on any cable in the use range.  The gel in the closure seals on contact.  Installation is literally a snap.  The gel wrap splice closure can be applied on all common compression connectors and low voltage cables.  Many in line mechanical connectors can be covered as well.

     The factory cured power gel silicone sealant in the gel wrap closure completely encapsulates the connection.  Since the gel is easily stretched and very stick, it basically forms around the cable and connector sticking to everything including itself.  Moisture cannot enter the splice.

     Gelwrap is available in a number of different sizes:

GelWrap 18/4-100

GelWrap 18/4-150

GelWrap 18/4-200

GelWrap 18/4-250

RNF-100

RNF-100 Thin Wall Uncoated Tubing

RNF -100 Tubing Available in Many Colors

     RNF-100 is a flexible, flame retardant, thin walled, general purpose heat shrinkable polyolefin (a modified polyethylene) tubing.  Available in many different colors (but the clear tubing is not flame retardant). 

     RNF-100 is ideal for wire jacketing, marking and color coding different wires and cables.  This tubing is sold with a 3:1 shrink ratio and an unlimited shelf life when stored under proper conditions. 

     Sold in rolls that can be anywhere from 25 feet long to 500 feet long; RNF is a multi functional product that is excellent to have on hand for many different possible uses.

     Here we see the sizing chart.  This chart shows catalog nomenclature, ID as supplied, ID as recovered, recovered wall thickness and standard feet per spool options. 

Heat Shrink Tubing (Medium Wall)

MWTM Heat Shrink Tubing

MWTM Medium Wall Shrink Tubing

     Raychem invented many different varieties of heat shrinkable tubing made specifically for many different applications.  As an example, we have our WCSM - rated to 1000 volts.  But what about cases where 1000 volt resistance isn't needed?  Is there a more cost effective option?  Of course there is: MWTM rated to 600 volts. 

     The radiation cross linked PE backing is just a little thinner than the WCSM.  Thinner backing means less electrical resistivity.  Pretty simple. 

     The sealant coated MWTM (you know it is sealant coated when it has a -S in the nomenclature) is for use on insulation and jacket repair up to 600 volts or for general sealing and rejacketing of polymeric or elastomeric insulated cables up to 35kV.  MWTM has a 3:1 shrink ratio and an unlimited shelf life when stored under normal conditions.

     See the different sizes available above.  The first letters are of course the material type (MWTM).  The first number is the supplied ID of the shrink tubing.  The second number (after the /) is the size which the shrink sleeve tube will recover to.  The third number (1200) is the length of the tube as supplied (they can be cut down simply and easily). 

     So, the MWTM 85/25-1200-S is a tube rated to 600 volts, supplied with an ID of 85mm which will shrink down to a 25mm substrate - it is supplied in a 1200mm long tube (48") and is coated on the inside with a sealant adhesive. 

FCSM - Flame Retardant Heavy Wall Tubing

FCSM - for 1/C Low Voltage Power Cable (2000 Volts)

     Some applications require a flame retardant material in order to meet specifications for a project.  In those cases, FCSM can be the perfect option with it's tough, crosslinked polyolefin construction that provides mechanical strength and cut through resistance, equal to or surpassing the properties of low voltage cable jackets. 

     FCSM's 3 to 1 shrink ratio and unlimited shelf life when stored properly make it simple and easy to have on hand for emergency repairs and quick use.  FCSM can be used as jacket repair on cables up to 35kV.  It is available in both internally coated with a sealant (-S) and uncoated (/U) varieties. 

     The first chart lists all FCSM that are internally coated sizes.  Simply look for your cable sizes and your connector sizes and you will quickly zero in on the size you need.  The plant does require that standard box quantities are met which means you may have to purchase more tubes than you need at any given moment. 

     The bottom chart shows sizes for uncoated FCSM tubes (no sealant inside).  For questions and comments about FCSM, please contact us today:  steve@jsicoatings.com
    

CRSM - CRSM-CT

CRSM and CRSM-CT

     In the Raychem world, we have two products with very similar names:  CRSM and CRSM-CT.  What's up with that?  What do those letters stand for?  Why not use more dissimilar names because that gets kind of confusing?  I don't know any of those answers -- but I do know what CRSM and CRSM-CT stand for.

     CRSM stands for "Cable Repair Sleeve - metric" -- or alternatively:  "Cable Rejacketing Sleeve - metric".  The "CT" at the end of the CRSM-CT stands for "Cable Tap" splice.  That probably didn't help very much did it?  I think the primary difference between the two products is that the CRSM-CT (which is expected to seal between two cables as seen below) is manufactured with a significantly thicker adhesive layer.  That thicker adhesive is sufficient to fill all cracks and voids and even properly seal the area between two different cables that are running parallel to one another. 

Here you see how the adhesive thickness of the CRSM-CT is able to properly seal around two cables

     Both products utilize the same backing and the same rail and channel closure system.  In both cases, the product is rated for use at 1000 volts when in direct contact with the cable splice / the current.  When used simply as a jacket repair, however, the products are rated to 35kV.  Quite a difference depending on what the application is!  You certainly would NOT under any circumstances use this product to seal a high voltage splice.  That could be deadly.

     CRSM is available for use on cables #8 up through 2000 mcm.  CRSM-CT (on a compression connector) can be used on #8 up through 500 mcm cable.  When installing on a split connector, you (of course) need a sleeve large enough to wrap around two different cables; so in those situations you are looking at installing on connections using # through #2 cable size.
