BPTM Busbar Insulation

BPTM Tubing

BPTM 15/6-A/U (50 ft roll)

    Raychem / TE Connectivity's medium wall, heat shrinkable BPTM tubing provides insulation enhancement and protection against flash over and accidentally induced discharge. 

     Particularly useful in confined spaces, BPTM tubing can be used on both circular and rectangular copper or aluminum busbars. On application of heat, the BPTM tubing shrinks snugly over the busbar profile ensuring that the required minimum wall thickness is obtained.  Raychem BPTM tubing can be installed easily during large scale production using an oven or in the field using a gas torch or hot air.  Raychem BPTM tubing is manufactured from a non-halogen based polymer which has excellent performance in high voltage environments and greatly reduces the noxious and corrosive effects in fire situations. 

    The use of TE's Raychem BPTM tubing allows equipment designers the freedom to reduce air spacing between busbars, such as in the manufacture of switchgear cabinets where space is at a premium.  Raychem BPTM tubing provides flashover protection up to 25kV. 

 Key Features:

• Exceptional insulation and long term reliability even at high continuous operating temperatures.
• Extremely durable, resists damage from solvents, ultraviolet light, weathering, mechanical impact and general wear and tear.

CSJA JCN/EG; All-in-one Cold Shrinkable Joints

CSJA JCN/EG

In-Line Cold Shrinkable Joints Specifically for 1/C Jacketed Concentric Neutral Cables (15-35 kV)

TE’s Raychem “All-in-One” CSJA is a cold shrinkable joint for 15 kV through 35 kV. It is designed to
splice jacketed concentric neutral (JCN) cables.

• Cable joint has a pre-expanded EPDM rejacketing sleeve and an integrated neutral sock.
  The “All-in-One” design is easy to install with minimal steps and short installation time
• A pre-expanded, single-piece silicone rubber joint body with high mechanical expansion capability
  allows a wide application range
• An ergonomically designed spiral holdout provides a smooth installation with low release forces.
• Total length of the splice body on the holdout is 14 to 19 inches providing a compact design.
• The Silicone rubber body provides high dielectric strength, high tear strength, low tension set, and
  excellent low temperature recovery
• Integrated electrical stress control enhanced by factory molded stress cones and Faraday cage.
• Void filling stress relief mastics are not necessary.
• Proven shield continuity concept. The neutral wires are connected externally. The integrated pre-expanded neutral sock is connected to the neutral wires by a constant force spring. This provides
  the metallic shielding system to the cable joint.
• The joint accepts both mechanical and compression connectors.
• Meets IEEE-404 requirements for 15 kV through 35 kV.

 Each silicone splice body is factory tested to include AC withstand and partial discharge in
accordance with IEEE-404 production tests.

CRSM Cable Repair Sleeves

     CRSM (Cable Repair Sleeves) are a multi-function heat shrink sleeve system used for a wide variety of cable repairs and low (1000 volt) splicing.  Utilizing a rail and channel mechanical closure system (which has been around since the 1960's), this product utilizes a high expansion backing and a thick adhesive sealant to cover many, many varieties of electrical repair/splice requirement.

     CRSM was invented in the 1970's.  Some might read that and think "wow; what an ancient technology; surely there is something newer out there."  Others (like me) would look at that and say "wow - 40 years of use and this product is still a leader in its field.  If there were problems with this product; they would certainly have been discovered by now."

     This product is available in a number of different sizes and widths.  The nomenclature is as follows:  the first number is the supplied ID of the tube (once the rail and channel is in place).  The second number is the fully recovered ID of the shrink sleeve.  The third number is the 'length' (some would say width) of the tube - or the coverage of the sleeve along the cable. 

Standard Sizes:

CRSM 34/10-200
CRSM 34/10-1200

CRSM 53/13-200

CRSM 53/13-1200

CRSM 84/20-750

How do I Splice a Medium Voltage Cable?

     How Do I Splice a Medium Voltage Cable?

     Boy, you would really think this was a simple question to answer.  It's not.  The first problem is that there are a number of different types of 'medium voltage' cable; and each can have different components (and thus different splicing requirements).  Let's look through a few of those.

1. Cable can be 'jacketed' or 'non-jacketed' (explanation here).
2. Cable can be 1/C or 3/C (explanation here).
3. Cable can be Armored (or not - explanation here).
4. Cable can contain 'concentric neutral cables' or 'copper tape shield' (explanation here).
5. Cable can be designed for anything between 5kV and 35kV.

     There may even be other different cable configurations.  The key though, is that when making a cable splice, the goal is to recreate the structure of the cable in the splice.  So, if your cable is 3/C Armored - then you need to be sure you are purchasing a splice kit which will be able to splice three conductors and be armored.

     As an example here in this post, I will look at the installation steps for splicing a 1/C, jacketed, concentric neutral cable at 25 kV. 

1. Make sure the HVS Medium Voltage Splice Kit you've purchased is correctly sized for your cable!
2. Remove the cable jacket to the dimensions shown on the installation sheet.
3. Fold back the neutral wires on 'side 1' and trim the neutral wires on the other side.
4. Use a tie wrap to keep unneeded concentric wires out of the way (to avoid damaging them)
5. Abrade insulation (abrading the PE improves the bond of the HVS)
6. Place heat shrink tube over cable and then install connector.
7. Apply SRM at semi conductor cutback (Stress Relief Material)
8. Apply SRM over connector
9. Apply Silicone Grease (SG)
10. Put black stress control tube in place and shrink with a gas torch.
11. Apply red sealant butted up against the black stress control tube on the semi-con.
12. Position black/red triple layer tube in place and shrink.  Begin shrinking in the middle and move toward one end of tube.  Then come back to middle and work toward other end.
13. Connect and splice neutral wires and bend them to splice.
14. Install shielding mesh by spiral wrapping.
15. Position the wrap around shrink sleeve and secure the channel (to hold it in place).
16. Shrink the sleeve.
17. Congratulations, you've done it!
