The piercing wire clamp is an insulation-piercing connector used for quick cable splicing and branching in power lines. It is specifically designed for ABC cables (overhead insulated cables). Handan Jinmai Fastener Manufacturing Co., Ltd., a professional power fixture manufacturer, leverages the advantages of the Yongnian fastener industry belt in Hebei Province to provide customized piercing wire clamps with hot-dip galvanizing and corrosion protection. These clamps are suitable for power transmission and distribution systems with voltage levels of 1-35kV. The product's insulation-piercing structure allows for strip-free installation, significantly improving installation efficiency and ensuring line sealing.
1. Efficient Installation
Utilizing insulation piercing tine technology, the cable is directly pierced and connected without stripping insulation, reducing installation time by 50%.
The matching torque nut ensures even pressure distribution, preventing overpressure damage to the cable core.
2. Safe and Reliable
The housing is made of engineering-grade nylon, which is UV-resistant and age-resistant, and can withstand extreme environments ranging from -40°C to +120°C.
It is TUV-certified and complies with IEC/GB standards, with an IP68 waterproof rating to prevent electrochemical corrosion.
3. Flexible Adaptability
Compatible with a wide range of wire diameters (2.5-240 mm²), it is suitable for mixed copper and aluminum conductor connections.
The modular design offers optional single- or dual-pass configurations to meet complex topology requirements, such as T-branching and straight-line connections.
The Handan Jinmai factory utilizes a comprehensive quality control system:
- Material Reinforcement: The base is constructed from high-strength aluminum alloy (grade 6061-T6), hot-dip galvanized (zinc layer ≥ 86μm), and salt spray tested for over 1000 hours.
- Precision Machining: The piercing teeth are CNC-pressed, with a tip hardness of HRC 58-62, ensuring consistent penetration depth.
- Automated Assembly: The insulation layer is automatically injection-molded, and a built-in silicone seal provides a double waterproof seal.
Voltage Ratings: 1kV, 10kV, 20kV, 35kV
Punch Capacity: Maximum insulation penetration 3.5mm
Mechanical Strength: Tensile Load ≥ 12kN, Torsion Angle ≤ 5°
Electrical Performance: Power Frequency Withstand Voltage 45kV/1min, Lightning Withstand Voltage 100kA
