Description
Use: YH type welding machine cable is suitable for secondary side wiring and welding clamp for secondary side to ground voltage of AC 200V and pulsating DC 400V.
Features:
The permissible operating temperature of 2451EC81(YH) and 2451EC82(YHF) conductors shall not exceed 65℃.
Permissible operating temperature of YH 85℃ conductor shall not exceed 85℃.
YHF type has certain characteristics of oil resistance and non-burning.
The long-term permissible operating temperature of EH cable conductor does not exceed 70℃, with good wear resistance and certain oil resistance.
Overview: Welding machine cable is suitable for welding machine secondary side wiring and welding clamp connection special cable, rated ac voltage is not more than 200V and pulse DC peak 400V.
The structure is single core, made of multi-stranded soft wire. The conductive wire core is wrapped with heat-resistant polyester film insulation tape, and the outermost layer is made of rubber insulation and protection
Set as a protective layer.
Application requirements:
(1) Welding machine cable is working under the condition of low voltage (maximum voltage is 200V) and large current, which requires a certain heat resistance.
(2) The long-term allowable working temperature of the cable shall not exceed 65℃.
(3) The cable is frequently moved, twisted and released, which requires softness and good bending performance.
(4) It is easy to be scratched and rubbed by sharp steel members in the process of application, so it requires good mechanical properties such as insulation, tear resistance and wear resistance of cables.
(5) the use of complex environmental conditions, such as sun, water boiling, contact mud, oil, acid and alkali liquid, etc., requires a certain degree of weather resistance and oil resistance, solvent resistance.
(6) Sometimes encounter hot welding parts, requiring good heat resistance deformation.
(7) Often move, require small diameter, light weight.
Because the electrical performance of this kind of cable is not high, and the use of complex environmental conditions, it is not appropriate to meet various complex environmental factors in the structure.
When using, pay attention to improve the use conditions to prevent external damage. Welding machine cable model and parameters:
