Welding cable -YH/YHF uses copper conductor and ethylene propylene rubber (EPR) insulation. Common models include YH and YHF welding machine cables, which are specially used for high current and low voltage welding scenarios. The quality is ensured by bending test (no breakage after repeated bending), burning test (flame retardancy) and thickness test (no pores and eccentricity).
Rated Temperature: Long-term working temperature ≤ 65℃
Conductor: Made of multiple strands of oxygen-free copper wire
Insulated: Heat resistant polyester film or natural rubber mixture
Sheathed: Neoprene or natural rubber blend
Wire core design: Single wire core structure, thick wire body, can carry large current
Models and selection points of welding cable
YH: General purpose, insulation and sheath in one, made of natural rubber, suitable for general welding
scenarios.
YHF: Enhanced, double-layer sheath (chloroprene rubber + rubber mixture), better oil resistance, suitable
for oily environment.
