35KV Heat Shrinkable Power Cable Accessories joint

Standard: IEC60502 GB-12706 Main material: polyolefin Types: *Cross-linked *1-core, 3-core; Property: 1. Flame-retardant, rapid shrinking, non-cracking, and simple installation. 2. Highly resistance to extreme temperature, atmospheric pollution and weather conditions. 3. Insulation components are resistant to fungus, copper corrosion, water and ultra-violet rays. 4. Hot melting adhesed lining in insulation components provides excellent waterproofing property. Advantage of Straight joints: 1. With 3-layer technology, more safe and reliable; 2. With long insulation tube, resolved the problem of creepage. CablesThe joints are designed for 1-and3-core screen polymeric insulated cables.
