Introduction to Welding Machine Cables

Welding wires are welding machine cables. Welding machine cable (YH cable), also known as high-strength rubber sleeve welding machine cable, commonly known as welding handle wire, is a type of YC cable (universal rubber sleeve cable).

The structure of the welding machine cable is a single core, usually consisting of multiple copper wires forming a copper wire group, and multiple copper wire groups forming the conductor part of the welding machine cable. Therefore, the YH cable body is relatively thick, with hundreds of copper wires. Multiple sets of copper wires are surrounded by a layer of heat-resistant polyester film insulation. The insulation layer is generally made of pure natural rubber, and the copper wire is made of oxygen free copper, in order to ensure the good conductivity of the wire core and the safety of the cable.

characteristic

1. The YH cable operates under low voltage (up to 200V) and high current conditions, requiring a certain level of resistance.

2. The long-term allowable working temperature of welding wire and cable should not exceed 65 ° C.

3. The motor oxime lead wiring cable frequently moves, twists and releases, requiring softness and good bending performance.

4. During discharge, it is easy to be scratched and rubbed by sharp steel components, so it is required that the cable insulation has good mechanical properties such as tear resistance and wear resistance.

5. The operating environment is complex, such as exposure to sunlight, boiling water, contact with muddy water, engine oil, acidic and alkaline liquids, and requires certain weather resistance, oil resistance, and solvent resistance.

Sometimes it may come into contact with hot welded parts, requiring good heat resistance and deformation resistance.

7. Frequent movement requires a small outer diameter and light weight. Due to the low requirements for the electrical performance of this type of cable and the complex operating environment, it is not suitable to meet various complex environmental factors in terms of structure. When using it, attention should be paid to improving the operating conditions to prevent external damage.

Specification and model

1. YH cable, insulated and sheathed in one layer, with a thickness of over 1.8 millimeters, made of a natural rubber mixture;

YHF cables have two types of coating layers, one is a chloroprene rubber mixture, the other is a rubber mixture used as insulation material and a chloroprene rubber mixture used as sheath.

What are the general specifications of welding machine cables? The specifications of ordinary welding machine cables include 16 square meters, 25 square meters, 35 square meters, 50 square meters, 70 square meters, 95 square meters, 120 square meters, etc.

standard

Welding machine cables are suitable for the power connection of mobile electrical equipment with a rated voltage of 450/750V and below. The implementation standard for welding machine cables is GB/T 5013.6-1997 "Rubber insulated cables with rated voltage of 450/750V and below -6. Welding machine cables".

Precautions for the use conditions of welding machine cables:

The long-term allowable working temperature of cable conductors with a rated voltage of 450/750v is 60.

When a short circuit occurs (the longest duration shall not exceed 5 seconds), the maximum temperature of the cable conductor shall not exceed 160.

3. Laying environment temperature: not less than 0.

4. The minimum bending radius of the welding machine cable is 6 times the cable diameter.
