Raychem HVT-Z-80-G/SG

HVT-Z-80-G/SG

     Joint Specialists is now stocking HVT-Z-80-G/SG.  We keep a number in stock (and about 50 other Tyco Electronics / Raychem products) so feel free to check with us for current inventory levels.  We do ship most of our items same day from our warehouse in Conroe, TX.  

     Going to start a series where I highlight / spotlight one Raychem / Tyco Electronics product each day.  Today we are looking HVT-Z-80.  

     First the product summary:  5/8 kV, 1/C indoor/outdoor termination kit for copper tape, wire shield, and unishield cables.  

     Nominal use range:  #4 - #1 AWG 5kV or #6-#2 AWG for 8kV.  

     Insulation OD Range: .35-.60" (9-15mm)

     Max Cable Jacket Diam: .95" (24mm)

    

So, what comes in a kit?   

This is the kit you get when you buy an HVT-Z-80-G/SG

Let's take a closer look at this though, breaking down into smaller pictures:

Raychem Red non-Tracking Tube and 2 Red Mastic Strips

1 Yellow Angle-cut mastic strip and 2 strips of copper backed tape

Solder blocked braid and a ground clamp spring

     That is what you will get every time you order a single HVT-Z-80-G/SG.  

     Now let's take a look at an installation video for HVT-Z (not 80)

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
