In today's social life, people's dependence on electricity is increasing day by day, and the requirements for the security of power grid power supply are getting higher and higher, especially the higher requirements for urban power grids. Therefore, it is one of the timely and effective measures to replace bare wires with insulated cables in the power supply lines of the city network. At the same time, the fittings should also take corresponding measures to make them have insulating functions. There are two methods. One is to apply insulating materials and design new fittings with insulating functions. The second is to design an insulating cover for the hardware to achieve the insulating effect.

Product Description

C-type clips are wire-connection type power connection fittings, which are mainly used for T-connection or jumper wire in non-load-bearing positions of overhead insulated wires, aluminum stranded wires, steel stranded wires and copper wires. The wire clamp is made of high-strength special aluminum alloy with good electrical conductivity. The structure is composed of a reasonable C-shaped and hinged wedge. When the hinged wedge is under the action of external force, the wire is pressed between the clamp shell and the wedge. . When the wire expands and contracts, the C-shaped structure should have the elasticity, and always maintain a lasting and constant contact pressure between the wire clip and the wire. It changes with the external environment and load conditions, and the contact pressure is inconvenient, which meets the best requirements for continuous connection. The design is more user-friendly; the fastening screws and nuts are made of stainless steel; the spring washer is added to enhance the reliability of the wire clip.

Features

1. Contact performance: the contact surface between the clamp and the wire is large, the clamping force is constant, and the branch resistance ratio is between 0.85-0.9;

2. Overload capacity: the overload capacity reaches more than 2 times of the rated current;

3. Firm performance: high-strength material, fastened with stainless steel bolts, reliable connection, not falling off;

4. Thermal cycle performance: good thermal cycle performance, always running below the branch resistance ratio of 1;

5. Installation: easy installation and disassembly, suitable for high-altitude operations;

6. Energy-saving performance: The material is made of high-strength special aluminum alloy, without electromagnetic loss, anti-corrosion and anti-oxidation. Small contact resistance, good thermal cycle performance, strong overload capacity, excellent energy saving, easy installation, maintenance-free, zero failure, long life and other excellent quality. When selecting, whether it is a power transmission line or a distribution line, only one connection is required first.

Installation Notes

C-type clip is suitable for steel core aluminum stranded wire, overhead insulated wire, aluminum stranded wire, aluminum clad steel wire, copper wire connection and jumper. It is a non-load-bearing connection metal. Installation does not require aluminum packaging, and the production is simple and convenient.

1. Determine the model of the wire clip according to the type of wire and the size of the main wire and the branch wire. Please carefully check whether the type and size of the wire are consistent with the marking on the wire clip. For example: the main wire is ACSR LGJ-240, and the branch wire is For overhead insulated wire JKLYJ-185, the selection of wire clip should be KEYI-JCI3. It is the same as one of the wires marked on the wire clip: LGJ240 to JKLY185.

2. Put the wire into the groove of the wire clamp, adjust the position of the main wire and the branch wire, the female wedge corresponds to the large (main) wire, the inner wedge corresponds to the small (branch) wire, insert the bolt from the back of the wire clip, and adjust It is in the middle of the wedge. Use a wrench to twist the nut in and flatten the hinge block. (Note: After completing the installation, be sure to check whether the wedges are flattened and the wires are compressed.)

3. Uninstallation Loosen the nut. The wedge can be arched upwards.
