3M Introduces First High-Voltage Cold Shrink Termination for Reduced Wall Cable.AUSTIN, Texas -- 3M expands its line of cold shrink products for high-voltage applications with the first termination kits for 69/72,5kV reduced-wall cable. The first high-voltage cold shrink product, a termination kit for 69kV standard-wall cable, was introduced in 2005. The 3M cold shrink silicone rubber Noun 1. silicone rubber - made from silicone elastomers; retains flexibility resilience and tensile strength over a wide temperature range synthetic rubber, rubber - any of various synthetic elastic materials whose properties resemble natural rubber termination kits QT-III, 7672-S-8 (RW) for 69/72,5kV are designed for indoor or outdoor use and to be highly reliable - they meet or exceed the requirements of IEC (International Electrotechnical Commission, Geneva, Switzerland, www.iec.ch) An organization that sets international electrical and electronics standards founded in 1906. It is made up of national committees from over 60 countries. IEC - International Electrotechnical Commission 60840 for 72,5kV, and solid dielectric dielectric (dī'ĭlĕk`trĭk), material that does not conduct electricity readily, i.e., an insulator (see insulation). A good dielectric should also have other properties: It must resist breakdown under high voltages; it should not insulation, such as PE, XLPE XLPE Cross Linked Polyethylene and EPR EPR Electron Paramagnetic Resonance EPR Extended Producer Responsibility EPR Electronic Patient Record(s) EPR Emergency Preparedness and Response (US DHS) EPR Endpoint Reference EPR Ethylene-Propylene Rubber shielded high-voltage cables. The new 3M termination is easier to install than other termination technologies, requiring no tools or heat source. Its light weight means that a crane is not required to install the termination. The simpler installation process can make possible a lower total installed cost and help reduce craft errors that may threaten reliability. This new termination kit is designed to accommodate a wide range of cables and solid dielectric insulations in thicknesses of 400-mil to 470-mil (10.2 to 11.9 mm). It is rated for 325kV BIL BIL Brother-In-Law BIL Billion BIL Bilateral BIL Band Interleaved by Line BIL Basic Impulse Level (electrical power switches) BIL Basic Insulation Level (IEC) performance levels and covers a conductor size range of 250-2000 kcmil (120-1000 square millimeters). Since first developing cold shrink technology for low- and medium-voltage applications more than 30 years ago, 3M has made a series of improvements to this technology. 3M cold shrink QT-III termination kits have been shown in field experience and laboratory tests to be reliable, even in challenging environments. Once applied, the cold shrink tube creates a dynamic, compressive com·pres·sive adj. Serving to or able to compress. com·pres  sive·ly adv. environmental seal and electrical interface - without sealants or adhesives - and resists ultraviolet radiation, ozone and industry-approved cable cleaners.
