Features The external protection layer adopts a high-strength protective shell and a waterproof and insulation sealing structure, which has good mechanical and sealing properties and excellent corrosion resistance, ensuring long-term and safe running under harsh environments;
The joint is compact and easy to install, the creepage distance inside the rubber insulation is long and the design margin is large, guaranteeing long-term operation, especially in a particularly damp area.
Good explosion-proof performance, which prevents fragmentation from accidents and endangers personal and equipment safety.
The outmost layer is protected by a GRP enclosure and the interior is painted with waterproof adhesives to strengthen the resistance to water and explosion.
Type tested according to IEC 60840, GB/T 11017, IEC 62067, and GB/T 18890. Dimensions
