3M Adds Cold Shrink Joint Kits to 69-kV Line

The new 3M Cold Shrink Joint Kits QS-III join the 3M Cold Shrink Termination Kits QT-III to complete 3M’s line of 69/72.5-kV cable accessories for power transmission and distribution, petrochemical, transportation and other heavy industry applications.

The cold shrink joint body is a one-piece molded design made of specially formulated silicone rubbers and the jacketing is made of EPDM rubber for physical protection. Each joint is pre-tested in the 3M factory before it is shipped.

These kits contain a 69-kV (IEEE)/725-kV (IEC) class joint for connecting polymeric insulated cables. The new joints cover conductor ranges up to 2000 kcmil (1000mm²). 3M technicians provide training and project support in the field for these high-voltage cold shrink accessories.

3M Cold Shrink Joint Kits QS-III have been in extensive field trials for the past 12 months and have been installed successfully in Europe and the United States. 3M’s first entry into the high-voltage market was with 3M Cold Shrink Termination Kits QT-III for 69 kV/72.5 kV. Cold shrink technology has proven to be highly reliable in the field, and because cold shrink products do not require tools or torches to install, they save time and money.
