3M 7000005950 – Frequently Asked Questions

1) What conductor sizes does the 3M 8428-12 cold shrink insulator fit?
The 8428-12 covers conductors from 600 kcmil up to 800 kcmil (300 to 400 mm2), single conductor. If your cable is smaller than 600 kcmil, this size will over-shrink past its range and you want a smaller tube in the 8428 family.
2) Can I use the 3M 8428-12 on medium voltage shielded cable?
No. The 8428-12 is a 1 kV, low voltage insulator for non-shielded applications, intended for primary insulation of solid dielectric insulated wire and cable splicing rated to 1000 volts. For 5 kV and above on shielded cable you need a rated medium voltage cold shrink splice kit, not this tube.
3) Do I need a torch or heat gun to install the 8428-12?
No heat and no tools. It's a cold shrink tube: you position it over the joint and pull the core out, and the EPDM rubber contracts on its own. That's the reason crews use it in vaults, manholes, and anywhere a flame is not allowed.
4) What jobs is the 3M 8428-12 cold shrink insulator actually used for besides splices?
Three things beyond straight splice insulation: sealing terminal lug barrels, sealing conduit couplings, and covering conduit-to-cable breakouts. The catalogued application is insulation, mechanical protection, and repair, so it also works as a jacket repair sleeve on damaged low voltage power cable.
5) Will the 8428-12 hold up outdoors in freezing winters and hot duct banks?
Its operating range is -40 to 90 degC (-40 to 194 degF), which covers northern winter exposure and the heat of a loaded conductor in a duct bank. The EPDM compound carries no chlorides or sulfur, so it won't attack the connector or cable it's sealing.
6) Can the 8428-12 be used on aluminum conductor cable?
Yes, it's specified for aluminum conductor power cable, single conductor. The tube itself is an insulating and sealing sleeve, so it goes over whatever compression or mechanical connector you've already made up, as long as that connector stays within 8 inches long.
7) How many 3M 8428-12 insulators come in a case?
Ten per case. For a three-phase 600 kcmil splice you're using one per conductor, so a case covers roughly three sets of three-phase terminations with one spare.
8) Is the 3M 8428-12 RoHS compliant and where is it made?
It is RoHS 2011/65/EU compliant without exemption, and it's manufactured in the United States. Worth noting for spec packages: it is not halogen free.
