Cold shrink cable accessories product introduction:
Cold-shrinkable cable accessories are components that use high elastomer materials (commonly used silicone rubber and ethylene-propylene rubber) to be injection vulcanized in the factory, then enlarged and lined with plastic spiral supports to form various cable accessories.
Medium Voltage cold shrinkable cable accessories products are suitable for 12/20kV PVC, XLPE, and EPR single-core, two-core, three-core, four-core, and five-core power cables. Cold shrinkable cable accessories have the advantages of small size, easy and rapid operation, no need for special tools, wide application range and few product specifications. Compared with heat-shrinkable cable accessories, it does not require fire heating and is widely used in various fields such as electric power, petrochemicals, metallurgy, railways, and port construction.
Product execution standards: IEC60502.4, GB/T12706.4
