3M 7642-T-110 Cold Shrink Indoor Termination Kit 5-15KV

Product Description

The 3M 7642-T-110 is a cold shrink indoor cable termination kit rated for 5 to 15 KV with a BIL rating of 110 KV. It is designed for use with concentric neutral and jacketed concentric neutral cables and installs without heat or open flame, using 3M cold shrink technology. The silicone rubber tubular insulator provides high-K stress control in a compact, one-piece design. Licensed electricians and cable splicers install this kit on medium-voltage power cable systems where a clean, reliable indoor termination is required. Cable insulation outer diameter range is 0.64 to 1.08 inches.

This termination kit is suited for indoor medium-voltage applications across commercial and industrial power distribution systems. It accommodates concentric neutral and jacketed concentric neutral cable constructions. Supported conductor sizes vary by voltage class: 4/0 AWG to 400 KCMIL at 5 KV (100 percent and 133 percent insulation levels), 3/0 AWG to 300 KCMIL at 8.7 KV (100 percent and 133 percent), and 2 AWG to 4/0 AWG at 15 KV (100 percent and 133 percent). The single-conductor, single-termination design makes it appropriate for phased or individual cable termination work in switchgear, transformers, and similar equipment.

Key Features

• Cold shrink installation requires no heat gun or torch, reducing installation time and risk
• Hi-K silicone rubber provides integrated stress control without a separate stress cone
• One-piece tubular design simplifies handling and accommodates a wide conductor size range
• Compact profile supports installation in restricted spaces such as switchgear cabinets
• Includes two mastic seal strips for moisture sealing at the cable jacket
• Meets IEEE applicable standards for medium-voltage cable terminations

Compatibility

Designed for use with concentric neutral and jacketed concentric neutral medium-voltage cables with insulation outer diameters from 0.64 to 1.08 inches, across 5 KV, 8.7 KV, and 15 KV voltage classes at both 100 percent and 133 percent insulation levels. Lug connector is not included and must be sourced separately.

Installation Notes

Installation should be performed by a qualified electrician or certified cable splicer in accordance with applicable local codes and IEEE guidelines. De-energize and verify the cable is isolated and grounded before beginning termination work. Cold shrink sleeves are expanded on a removable core — remove the core per the included instruction sheet to allow the sleeve to contract onto the cable without heat. Do not use the lug connector included as it is not part of this kit; select an appropriately rated lug for the conductor size and application.
