H type parallel groove clampDetailed product description：

Compared with traditional wire clamps, H-type wire clamps have the following obvious advantages:
1. H-type wire clamps can be used to crimp aluminum wire to aluminum wire, aluminum wire to copper wire, as well as to crimp wires of the same or different diameters.
2. The H-type wire clamp is designed with an enlarged anode, without copper aluminum transition issues, and will not corrode.
3. The H-type wire clamp is filled with anti oxidation protective oil, which can prevent corrosion and enhance conductivity. The structure is simple and integrally formed, ensuring product quality. When using hydraulic tools for crimping, the quality of the crimping can be guaranteed.
4. The H-type wire clamp tightly covers the wire after crimping and connecting it, rather than locally contacting the wire. The current passes through the complete contact surface, with uniform distribution, low resistance, low temperature rise, few faults, and good power supply reliability.
5. The H-type wire clamp only requires 6 specifications to fully meet the crimping connection needs of all 16-240mm ² aluminum stranded wires, aluminum core insulated wires, steel core aluminum stranded wires, copper stranded wires, and copper core insulated wires. It can replace 5 specifications of GB2335.1 parallel groove clamp, 15 specifications of GB2335.2 jumper clamp, and 18 specifications of GB2340T clamp, totaling 38 specifications.
6. H-type wire clamps, due to their limited specifications, can alleviate inventory and capital backlog issues, as well as reduce human resources for warehouse hardware construction, procurement, and warehouse management. Small specifications, light weight, easy to carry, can reduce the workload of construction personnel and increase work efficiency.
7. The H-type wire clamp crimping connection is fast, which is conducive to power fault repair, early power supply, and reduces the social harm caused by power outages, especially in traffic signals, furnaces, refrigeration, and high-tech industries.
8. The H-type wire clamp has good tension, resistance, and temperature rise conditions, with fewer faults, which can reduce power line energy loss and save national energy. It will not cause power outages or affect electricity sales revenue due to joint accidents.
9. The H-type wire clamp is lightweight and has good functionality. Replacing the parallel groove wire clamp with it can save a lot of national resources. Two clamps are required for the connection of each wire, and only one H-type clamp is needed. Due to the same purpose of use, the weight of the parallel groove clamp is about 9 times more than that of the H-type clamp.
10. When using H-type wire clamps for live work, only one is needed for each connection, and hydraulic pliers with insulated handles are used for crimping, making construction simple and preventing electric shock accidents for workers.
11. GB2335.1 Parallel groove clamps can only clamp aluminum stranded wires and steel core aluminum stranded wires, and cannot clamp copper stranded wires. They can only clamp wires of the same diameter and cannot clamp wires of different diameters, which greatly limits their functionality.
12. The parallel groove clamp is fastened with bolts and connected with aluminum sheets, resulting in a small contact area, uneven current distribution, high resistance, and high temperature rise. Moreover, its contact surface is difficult to avoid corrosion and accidents under wind and rain invasion.
13. When the parallel trench clamp is used for live work, two or more bolts are required at each joint. The operator needs to wear rubber gloves on both hands and leather gloves, and use a wrench tool to lock the nut. The action is not flexible and the construction difficulty is high, making it more prone to electric shock accidents.
14. Regardless of the type of bolt used for the parallel groove clamp, the torque applied to the nut should be appropriate and correct in order to maintain a good connection. However, in reality, the quality of on-site construction personnel varies, making it difficult to obtain an appropriate torque. Excessive pressure can cause bolt breakage or deformation of the connecting wire, while insufficient pressure can lead to high contact resistance and temperature rise, which can easily cause connection failure accidents, making it its biggest disadvantage.
