Cold Shrink Terminations

3M Cold Shrink : High Voltage Cable Joints & Cable Terminations
 

3M Cold Shrink Cable Terminations - Single Core Three Core - 11kV 24kV 33kVCold Shrink Terminations, by 3M, provide a modern technology answer to terminating low and high voltage power cables without resort to naked flames, gas torches or "hot-working" hassle.

Cold Shrink Terminations Installation
Cold shrink terminations installation involves fewer steps than the traditional heat shrink termination method - the effficiency of cold shrink terminations derives from a reduced part count compared to heat shrink terminations. The heating step is eliminated, along with heat shrink gas torches, burners and cannisters - reducing risk and potential cable jointer error. The simpler nature of cold shrink termination installation reduces field mistakes - 3M test reports document 30 to 50 years life cycle expectation for cold shrink terminations according to accelerated age testing.

Cold Shrink History
3M developed and patented cold shrink insulation technology in 1968 for cable terminating, cable jointing, cable splicing and insulation applications - the first cold shrink insulators were known as pre-stretched tubes (PSTs) or PST zip-core tubes. Consisting of an expanded rubber tube with a removable plastic core, cold shrink terminations satisfied a demand for a faster and simpler cable termination, splice or joint. 11kV-33kV 3M Cold shrink terminations are available from stock.

3M Cold Shrink Terminations to suit 3 core cables either indoors or outdoors.

3M Cold Shrink 7600 QT-III Cable Terminations - Technical Specification : 1) Electrical ratings : 90 degrees Celsius continuous operating temperature, 130 degrees Celsius emergency overload (Class 1 designated to IEEE-48). 2 Hydrophobicity - airborne contaminants deposited on cable termination surfaces can cause destructive leakage currents and discharge-initiated material erosion leading to high voltage tracking, flashover and cable failure. Hydrophobic silicone rubber and EPDM compounds provide 3M Cold Shrink Terminations with a long service life under rain, fog and drizzle weather conditions. 3 Oxidation - silicone Cold Shrink resists ozone, corona and weathering. 4 Impulse Flashover - 3M QT-III cable terminations exceed IEEE Standard 48-1996 BIL by 50%. 5 Industrial Contamination - 3M cable terminations subject to intense and extreme chamber testing to determine tracking performance (see download). 6 Dielectric Test - 3M QT111 Cold Shrink terminations conform to IEEE-48, CENELEC HD629.1 S1 and VDE 0278. 7 Pressure Leak Tests - excellent moisture sealed high voltage cable termination in accordance with IEEE-48-1996.
