Explosion-proof Shell (High-strength Fiber)
The Ankura-HFSBH (N) waterproof and explosion-proof fire protection shell is suitable for explosion-proof and fire protection of intermediate connectors. It can effectively prevent further damage to the power transmission lines when the intermediate connector of the cable explodes, thereby improving the reliability of the power grid operation. It is made through an overall winding process of special glass fibers, with excellent mechanical properties, acid resistance, and corrosion resistance. It can effectively prevent the cable from being damaged by external forces. In the event of an explosion and combustion accident at the intermediate connector of the cable, it can effectively prevent the shock waves and flames generated by the explosion, avoiding the occurrence of secondary disasters.
- Integral Kevlar fiber winding type.
- The integral winding type explosion-proof protective shell is suitable for joint installation in newly installed conditions.
- The automatic fire extinguishing device can be selected according to user requirements.
- This explosion-proof shell is easy to install and has wide adaptability. It can be installed outdoors, in tunnels, and in cable trenches and is not affected by various abnormal climates.
- This product has passed the short-circuit current test: 12kV 0.4s 50kA; it can truly and effectively prevent explosions and avoid secondary accidents.
- It is used for protection of non-company joint products. An installation diagram of the joint's external dimensions needs to be provided.
