QWhat is insulation material of welding cable?AWelding cable usually comes with rubber insulation, typically either Neoprene or Ethylene Propylene Diene Monomer (EPDM) rubber, and is designed to be fire (small sparks), water, oil, and abrasion resistant.
QHow to assure the quality of your cable productions?A1. Most of our products are certified.
2. Our Lab staff will test the material and check the process card before production.
3. The O.D tester is testing all the time during production, and the production line is always under control.
4. The product will be tested by Lab staff after finishing production.
QWhat are applications of flexible cable?AFlexible Cable applications are to withstand the extreme stress of flexing and motion. A few applications include: drag chain applications, applications with repetitive bending and torsion stress, machine tools, data processing equipment, robotics, assembly lines, automation networking, microprocessor and computer interconnects and many more.
QMain characteristics of split-phase metal sheath power cablesAWaterproof wire and cable research and development has been a problem in the main study, after many long and repeated experiments we can found that even if the insulating sheath is not broken, there will be some water or moisture seeped into the core of power cables. Thus, it is generally considered that improving three core waterproof cables to three single core waterproof cables structure is better when medium voltage power cables or low voltage power cables applied to real-life.
We can produce cables based on the structure of single core medium voltage waterproof power cable, then stranding three single core cables instead of three core cables. Water-blocking effect of improved water proof power cable will be better, and the structure become simple, it is not only save water blocking and cost, but also improve the carrying capacity and heat dissipation potential of power cables on the other hand, ease of manufacture, and easier to install. The most important is to prevent the ingress of moisture inside the cable, keep dry insulated core, to further extend the life of the cable.
Specifications of split-phase metal compartment power cables
1. Specifications of power cable core
Conductor should be metallized or non-metallized annealed copper, aluminum, or aluminum alloy which consistent with GB/ T3956 type 1 or type 2, it also can be bare copper or metallization annealed copper conductor consistent with GB T3956 type 5, Insulation, metal shielding (if any), cabling, inner sheath (if any), the outer jacket to meet GB /T12706 relevant standards.
2. Specifications of split-phase metal sheath
After the completion of phase metal sheath. we need test for cables inflate, the test should be met. cable filled 50-100KPa dry air or nitrogen, total length of the cable after the pressure equalization within 3h, the air pressure in the cable should not be reduced.
3. The integrated waterproof specifications of metal power cable
Cable finished product soaked in water 72 hours then the case of the surface except the insulating structure, observe the surface should be dry Phase metal sheath water poof power cable manufacturing process is simple, all aspects of performance are more excellent, and it is suitable for medium and low voltage cable selection.
QHow to identify good quality cable or poor quality cable?A1. Check printed label carefully, whether the printing is illegible. It means to see printed words on the label and the insulated sheath, if there are typos or printed shades, vague words, you need to pay attention. 2. Twist insulation sheath with hand, check whether it fades or lose word. Twist insulation sheath with your fingers, insulation sheath of poor quality cable is easy
to fade, especially red insulation sheath and printed word is easy to rub away. 3. Scratch or nip insulation sheath of cable with nails. it is poor quality cable if you can pinch off the insulation sheath. 4. Bend insulation sheath repeatedly, and check whether it will break after three to four times. If break, it is poor quality cable because its insulation sheath is very bad. 5. Fire the insulation sheath of cable, check whether it will self-ignite when fire off. If it will self-ignite, it is poor quality cable. 6. Check the conductor. The conductor of cable is common aluminum and copper if the conductor color is dark and no metallic luster, it is poor quality cable. 7. Measure inner diameters and outer diameters, and then weigh the cable. Measure the inner and outer diameters of cable insulation sheath the tolerance is ±10%. If it exceeds the tolerance it is poor quality cable.
QAre you a manufacturer or trading company?AWe are a leading and professional manufacturer of cable and wire, including power cable up to 500kv, ABC bare conductor building wire, control cable instrument cable, welding cable, rubber cable and so on, with high quality.
