The insulation piercing wire clamp is a special connector that can achieve electrical connection between the main line and the branch line without stripping the insulation layer of the wire in advance. It uses the internal precision piercing blade structure. When the installation bolt is tightened, the blade penetrates the insulation layer of the wire and forms a reliable, low-resistance electrical contact with the metal conductor. This design greatly simplifies the installation process and improves construction efficiency, while ensuring the long-term stability of the connection and excellent electrical performance. The insulation piercing wire clamps provided by Handan Jinmai are suitable for aluminum stranded wire, aluminum alloy stranded wire and copper stranded wire insulated wires of various cross-sections.
1. No need to strip insulation, efficient installation: No need to strip the insulation layer of the wire, saving a lot of installation time, reducing labor intensity and the risk of errors, especially suitable for live work.
2. Reliable electrical connection: The precision-designed puncture blade ensures low-resistance, high-conductivity contact with the conductor, low temperature rise at the connection point, and stable electrical performance.
3. Excellent waterproof sealing: The high-quality insulating shell (usually engineering plastics such as polycarbonate PC) and the built-in silicone sealing gasket provide excellent waterproof, moisture-proof and dust-proof performance, effectively protecting the connection point from environmental erosion.
4. Strong mechanical properties: The sturdy shell and high-strength puncture and compression structure design ensure that the wire clamp can withstand wire tension, wind load and certain mechanical impact.
1. Raw material selection: Strictly select high-quality raw materials that meet international standards (such as ANSI, IEC) and national standards, including high-strength and high-conductivity metal parts (such as piercing blades, conductors, bolts and nuts, commonly made of copper alloy, high-carbon steel tinning, etc.), as well as anti-aging and weather-resistant engineering plastics (such as PC) and long-lasting elastic sealing materials (such as silicone rubber).
2. Precision stamping and processing: Metal parts are formed by precision stamping, turning, forging and other processes to ensure accurate dimensions and meet strength standards. The edge of the piercing blade is specially treated and precision ground to ensure the sharpness of the piercing and the flatness of the conductive contact surface.
3. Injection molding: The insulating shell is injection molded with high-quality molds to ensure a complete structure, smooth appearance and reliable insulation performance.
4. Rigorous assembly: In a clean workshop environment, skilled workers or automated equipment accurately assemble metal conductive parts and seals into the insulating shell. The assembly process strictly controls the fit and preload of each component.
Applicable voltage level: Usually suitable for medium and low voltage distribution systems, such as 1kV, 10kV, 20kV, 35kV, etc. Specific models correspond to specific voltage levels.
Applicable conductor types: Insulated conductors of aluminum stranded wire (AAC), aluminum alloy stranded wire (AAAC), copper stranded wire (Cu).
Applicable conductor cross-sectional area range: Covers a wide range of cross-sectional areas, for example: main line: 16mm² to 300mm²; branch line: 16mm² to 150mm² (the specific range varies depending on the model). A single product can usually cover a certain range of wire diameters.
Contact resistance: ≤ 1.1 times the resistance of the same length wire or meet the requirements of relevant standards (such as IEC 61284, ANSI C119.4), ensuring low-loss connection.
Insulation resistance: ≥ 1000 MΩ (in dry state), ensuring excellent insulation performance.
