Import Customized Insulation Piercing Connector — Buy in wholesale FOB from Supplier in China

The customized insulation piercing connector from Hebei Sali Electric Equipment Manufacturing Co., Ltd. is a mechanical device designed to establish electrical contact with insulated overhead conductors without stripping the insulation. It is available in multiple models including KWLW-1, KWLB-1, and KW4-150-2P, each rated for conductor cross-sections from 4mm² to 150mm². The connectors are engineered to pierce through the insulation layer using a precision-cutting blade and maintain a low-resistance connection between copper and aluminum conductors.

The housing is made from high-strength, UV-stabilized thermoplastic with an IP68 rating for waterproofing and corrosion resistance. Internal components include a brass or aluminum piercing blade, a self-sealing rubber gasket, and a torque-controlled moment nut that ensures consistent piercing pressure. The design conforms to DL/T765.1-2001 and GB/T13140.4-1998 standards. The connector’s insulation strength withstands up to 12kV and has passed glow wire testing per GB/T5169.4. It is suitable for medium-voltage distribution networks up to 1kV.

These connectors are widely used by utility companies and electrical contractors for service drops, branch connections, and grounding applications on overhead lines. Buyers include municipal power providers, renewable energy installers, and infrastructure contractors in regions with aging overhead networks. Packaging is in sealed plastic bags with internal foam inserts, 100 units per carton. Trade terms are FOB Tianjin Port, with lead times of 20 to 25 days. Payment is accepted via T/T or L/C. Custom configurations for non-standard conductor sizes are available upon technical review.
