The insulation piercing clamp is applicable to the new cable T-connection products of small capacity power and
lighting power supply systems. The use of puncture clamp is another cable T-connection mode after the cable
distribution box and pre branch cable. It has the characteristics of more safe and reliable power distribution,
simple installation, waterproof, low environmental requirements, maintenance free, and more economical. It
can be used in low voltage power and lighting distribution lines such as high-rise buildings, civil residences,
street lamp power distribution, outdoor overhead lines, etc. It can be installed in shafts and outdoors.
Structure composition and type selection
The puncture clamp is connected by a screw with a torque screw through two insulation supports separated up
and down. Two pieces of conductors made of special alloy that can contact the conductor at multiple points are
hidden in the insulation support. The puncture clamp is equipped with torque nut and puncture structure. The
torque nut is used to ensure constant contact pressure, ensure good electrical contact, and together with the
puncture structure, make the installation simple and reliable. During installation, it is only necessary to visually
check whether the torque nut is broken, and whether the wire position is appropriate to ensure reliable quality.
After testing, the contact resistance and line insulation resistance meet the requirements of the construction specifications, and the temperature rise at the joint part of the loaded power on test run is normal The use of
the puncture clamp has little impact on the mechanical and electrical properties of the trunk line. Now the
puncture clamp has a complete range of models, which can easily meet the T-connection needs of the trunk
line of ordinary power lines.
Product characteristics
Mechanical property: under the action of wire breaking force, the connector has no crack. Waterproof and insulation performance: the underwater insulation strength is up to 15KV (medium voltage)/6KV
(low voltage). Temperature rise performance: the temperature rise of connector is lower than that of connecting
wire when large current passes through.
Electrical performance: specially made torque bolt ensures constant puncture pressure and good electrical contact.
Easy operation: puncture structure, no need to cut, no need to peel the insulated wire.
Wide scope of application: applicable to copper copper butt joint, aluminum aluminum butt joint, copper aluminum transition, and reducing conductor connection: low-voltage (1KV), medium voltage (10KV) cable insulation piercing connector. They are respectively suitable for aerial cable (insulated, bare wire) branch connection, insulated incoming cable branch connection, building power distribution system branch connection, street lamp power distribution system, etc. Low voltage (1KV), medium voltage (10KV) underground power grid (directly buried, cable trench) special cable insulation piercing connector and accessories. It is mainly used to branch insulated cables in the underground branch
box, and is the best choice for underground engineering of power grid.
Product features 1. The installation space can be ignored. 2. It does not need maintenance and can be installed in narrow spaces such as bridge, box, pipe and cable trench
without occupying effective area. 3. The construction speed is extremely fast: it only takes about 3 minutes for each branch. 4. Save time, labor and expense. 5. Only matching ordinary socket wrench can be used for installation. 6. Insulation puncture connection, waterproof and moisture-proof. 7. It is resistant to tension, distortion, vibration, acid and alkali corrosion.
