Basic introduction of insulated puncture clamp

When connecting the cable branches of the puncture clip, insert the branch cable into the branch cap and determine the location of the main branch. Use a socket wrench to tighten the torque nut on the wire clip. With the tightening of the torque nut, the two insulators with puncture blades in the upper and lower part of the wire clip gradually close. The puncture blade also began to puncture the insulation layer and metal conductor of the cable. When the sealing degree of the sealant gasket and insulating grease and the contact between the piercing blade and the metal body achieve the best effect, the torque nut automatically falls off. At this time, the installation is complete and the contact point sealing and electrical effect achieve the best effect.

Product Profile:
Puncture structure, simple installation, no need to peel the insulated wire;
Torque nut, constant puncture pressure to ensure good electrical connection without damage to the wire;
Self-sealing structure, moisture-proof, water-proof, anti-corrosion, prolong the service life of insulated wire and clamp;
Using special contact blade, suitable for copper (aluminum) butt and copper aluminum transition;
The electrical contact resistance is small, the contact resistance is less than 1.1 times of the equal length branch wire resistance, in line with DL/T765.1-2001 standard;
Special insulated housing, anti-light and environmental aging, dielectric strength > 12KV;
Arc design, suitable for the same (different) diameter wire connection, wide connection range (0.75m2-400mm2).

Performance test:
Mechanical properties: the grip strength of the wire is greater than 1/10 of the breaking force of the wire, which meets the requirements of GB2314-1997;
Temperature rise performance: in the case of high current, the temperature rise of the wire clamp is connected to the temperature rise of the wire;
Thermal cycle performance: in line with GB/T2317-2000 power fittings thermal cycle test standards;
Waterproof insulation performance: meet the relevant test requirements of GB/T13140-1998 Part 2 standard;
Corrosion resistance: three 14-day cycle tests in sulfur dioxide and salt spray environment;
Environmental aging performance: Exposure to UV, dry, and humid environments, temperature changes, and thermal shock for six weeks;
Fire resistance: The insulating material of the connected device is subjected to the scorching wire test, in accordance with the requirements of Chapter 4-10 of GB/T5169.4.

Three advantages
1. Easy installation: do not need to strip the insulation of the cable can be made cable branch, the joint is completely insulated, do not need to cut off the main cable, can be made at any position of the cable branch. Easy and reliable installation, only need to use socket wrench, can be installed with electricity.
2. Safe use: the joint is resistant to distortion, shock, waterproof, flame retardant, anti-electrochemical corrosion aging, no maintenance.
3. Cost saving: Minimal installation space, saving bridge and civil construction costs. Building applications, do not need terminal box, distribution box. No cable return, save cable investment.

Installation method
1. Adjust the clamp nut of the puncture wire to the appropriate position, and fully insert the branch line into the cap.
2. Insert the main line. If the main line has two layers of insulation, peel off a certain length of the outer insulation skin at the connection position.
3. Put the main/branch line in the proper position and keep it parallel. Tighten the nut by hand first and fix the clamp.
4. Use the corresponding size of the sleeve plate to tighten the nut evenly until the top breaks off and the installation is complete.

Product classification
The insulated puncture clamp can be divided into 1KV, 10KV, 20KV insulated puncture clamp according to voltage classification.
According to the function classification, it can be divided into common insulation puncture clip, electrical grounding insulation puncture clip, lightning and arc protection insulation puncture clip.
