YH rubber sheathed cable

What is the difference between YH cable and YHF cable

Electric welding machine cable (YH cable) is the full name of high-strength rubber sheathed electric welding machine cable, commonly known as welding handle wire, which is a kind of YC cable (general rubber sheathed cable).

It is a special cable used for the wiring of the secondary side of the electric welding machine and connecting the electric welding pliers and the electric welding machine. Its characteristics are high resistance and low voltage. The working voltage is generally 450V to 750V. What is the difference between the YH cable and the YHF cable? The structure of the electric welding machine cable is The single core is generally composed of copper wires with multiple copper wires, and multiple groups of copper wires form the conductor part of the welding machine cable, so the YH cable is thicker and has hundreds of copper wires. It is wrapped with heat-resistant polyester film insulation. The insulating layer is generally pure natural rubber, and the copper wire is oxygen-free copper, so as to ensure the good conductivity of the core and the safety of the cable.

The specifications and models of commonly used electric welding machine cables are 16 square meters, 25 square meters, 35 square meters, 50 square meters, 70 square meters, 95 square meters, 120 square meters, etc.

What is the difference between YH cable and YHF cable Several characteristics of electric welding machine cable:

(1) The YH cable works under the condition of low voltage (the maximum voltage is 200V) and high current, and requires certain tolerance.

(2) The long-term allowable working temperature of the welding wire and cable should not exceed 65 degrees Celsius.

(3) The motor lead wire is frequently moved, twisted and released, requiring softness and good bending performance.

(4) It is easy to be scratched and rubbed by sharp steel components during deployment, so the cable insulation is required to have good mechanical properties such as tear resistance and wear resistance.

(5) The use of environmental conditions is complex, such as sunlight, water boiling, contact with muddy water, engine oil, acid-base liquid, etc., and requires certain weather resistance, oil resistance, and solvent resistance.

(6) Sometimes hot welding parts are encountered, and good thermal deformation resistance is required.

(7) Frequent movement requires small outer diameter and light weight. Due to the low electrical performance requirements of this kind of cable and the complex use of environmental conditions, it is not suitable for the structure to meet various complex environmental factors. Pay attention to improvement when using Conditions of use to prevent external damage.
