JBC 1.5-300mm² 1-10KV 75-600A Puncture clamp for insulated distribution line Branch connection device
Product Description
Insulation puncture clip is mainly composed of insulation shell, puncture blade, waterproof rubber pad and torque bolt. When connecting the cable branch of the insulation piercing clip, insert the branch cable into the branch cap and determine the position of the main line branch, then use a socket wrench to tighten the torque nut on the clip. The insulator of the puncture blade gradually closes, and at the same time, the arc-shaped sealing gasket wrapped around the puncture blade gradually adheres to the cable insulation layer, and the puncture blade also begins to pierce the cable insulation layer and the metal conductor. When the sealing degree of the sealing gasket and the insulating grease and the contact between the piercing blade and the metal body are effective, the torque nut will automatically fall off. At this time, the installation is completed and the sealing and electrical effects of the contact point are very good.
Insulation puncture clips can be divided into 1KV, 10KV, 20KV insulation puncture clips according to voltage classification.
According to the function, it can be divided into ordinary insulation puncture clip, electrical inspection grounding insulation puncture clip, lightning protection arc insulation puncture clip, fire insulation puncture clip
Product features and Advantage
Features:
1. The puncture structure is simple to install, and the insulated wire does not need to be peeled;
2. Torque nut, constant puncture pressure, ensure good electrical connection without damaging the wire,
3. Self-sealing structure, moisture-proof, waterproof, anti-corrosion, prolong the service life of insulated wires and clips
4. Using special contact blade, suitable for copper (aluminum) butt and copper-aluminum transition
5. The electrical contact resistance is small, and the contact resistance is less than 1.1 times the resistance of the equal-length branch wire, in line with the DL/T765.1-2001 standard
6. Special insulating shell, resistant to light and environmental aging, dielectric strength> 12KV
7. Curved surface design, suitable for the same (different) diameter wire connection, wide connection range (0.75mm2-400mm2)
Advantage:
1. Easy installation: the cable branch can be made without stripping the insulation of the cable, and the joint is completely insulated. There is no need to cut off the main cable, and branches can be made at any position of the cable. Easy and reliable installation, only need to use a socket wrench, it can be installed live.
2. Safe to use: The joint is resistant to twisting, shockproof, waterproof, flame retardant, anti-galvanic corrosion and aging, and requires no maintenance. Has been used successfully for over 30 years.
3. Cost saving: The installation space is extremely small, saving bridge and civil construction costs. For applications in buildings, there is no need for terminal boxes, distribution boxes, and cable return lines, saving cable investment. The cost of cable + piercing clip is lower than other power supply systems, only about 40% of the plug-in busbar, and about 60% of the prefabricated branch cable.
Product installation method
Installation of single screw insulation piercing clip:
1. Adjust the puncture wire clamp nut to the appropriate position, and completely insert the branch wire into the branch wire cap sleeve.
2. Insert the main line. If the main line has two layers of insulation, strip off a certain length of outer insulation at the connection position.
3. Put the main/branch line in the proper position and keep it parallel, first tighten the nut by hand, and fix the clamp.
4. Tighten the nut evenly with a socket wrench corresponding to the size until the top breaks and falls off, and the installation is complete.
Installation of twin-screw insulation piercing clips:
1. Unscrew the wire clamp and insert the main wire into the main wire groove. Do not twist the main wire and the knife ruler. Pay attention to whether the wire diameter range corresponds to this wire clip.
2. Put the branch wire into the branch wire slot. Note the same as above.
3. Tighten with a socket wrench. Disable open-end wrenches.
4. Note that the two nuts should be screwed down in sequence.
5. When tightened to a certain strength, the constant torque nut is broken, and the installation is completed
