Electric welding machine lansu wire, belongs to rubber insulated cable, the latest implementation standard is GB / t5013" rated voltage 450 / 250v and below rubber insulated cable ", including two types: yh ( high strength xiangtao welding machine cable ), is used for secondary cejiexian of welding machine and connecting electrode holder and electric welding machine, its characteristics are large current and low voltage.

Electric welding machine cable is single wire core, conductors are oxygen-free copper, copper wire diameter small, number of elements, generally made by Dorgan copper wire strands, and then Dorgan strands twisting, so the welding machine cable is thicker, copper wire hundreds of roots. Conductor outsourcing a layer of heat polymerization insulation. The cable of type yh, insulation and Nursing Home is one layer, the thickness is thicker, more than 1.8 mm, the material is a natural rubber mixture; The cable of the model yhf has two covering layers, one is neoprene mixture, the other is rubber mixture as insulation, and neoprene mixture as the sheath.

The specifications of electric welding machine cable are 16 square, 25 square, 35 square, 50 square, 70 square, 95 square, and 120 square.

Several characteristics of electric welding machine cable:

( 1 ) the yh cable operates under the condition of low voltage ( up to 200 v ) and requires a certain tolerance.

( 2 ) the long-term allowable working temperature of the wire cable shall not exceed 65 ℃.

( 3 ) motor lead wire cables frequently move, niurao and cast, requiring soft and good bending properties.

( 4 ) it is easy to be scratched and cleaned by the sharp steel components in casting, so the cable insulation tear, wear resistance and other mechanical properties are good.

( 5 ) the use of environmental conditions is complex, rurishai, Boil frost, contact slurry, oil, acid-base liquid, etc., requires certain weather fastness and oil resistant and solvent resistance.

( 6 ) sometimes the rehanjian is encountered and the heat resistance deformation is required.

( 7 ) moving frequently, requiring small outside diameter and light weight. Due to the low performance requirements of such dianlandian, and the use of environmental conditions, it is not appropriate to meet various complex environmental factors. Use attention to improve the use conditions to prevent external damage.
