12/20KV Cold Shrink Tubing

It mainly divided into the single core, two-core, three-core, four-core, five-cove, which is widely used in the terminals processing and middle connection of low-voltage electric cable. Cold Shrinkable cable accessories adopt the most advanced thchnology of cold shrinkable, dispense with using fire or others special tools. Only need to draw out the wires, when you prepare for installaion, and the elastomer will rapidly shrink and appress to the installation position. 

Used widely, high prominent anti-fouling, anti-aging, hydrophobicity and heat-resisting, cold-resisting performance. Especially suitable for areas of high altitudes, cold, wet, umidity, salt spray and heavy pollution. Popular for oil field, chemical industry, diggings, tunnel and others various inflammable and explosive locations. Manufacturing equipment advanced, automaticity high dependable performance.
