YJV cable supplier: What are the reasons for power cable heating?
To ensure the safe operation of power cables, when selecting wires and cables, the performance, layout, and surrounding environment of the cables should be considered, and fire-resistant cables can be selected.
During use, instrument cable heating may be caused by the following reasons:
1. The heating phenomenon of the cable during operation may be due to the conductor resistance of the cable not meeting the requirements.
2. Improper selection of cable type leads to a small cable conductor cross-section, resulting in overload during use. After long-term use, the imbalance between cable heating and heat dissipation leads to heating.
3. The cable is too close to other heat sources, affecting the normal heat dissipation of the cable, or when installing wires and cables, the arrangement is too dense, and the ventilation and heat dissipation effect is not good, which may also cause the cable to heat up during operation.
4. Poor joint manufacturing process, loose voltage connection, resulting in excessive contact resistance of the joint, also causing cable heating.
5. Poor insulation between cables leads to low insulation resistance, which will also generate heat during operation.
6. Local sheath damage of armored cables, after water ingress, causes slow damage to the insulation performance, leading to a gradual decrease in insulation resistance, and also causing the cable to heat up during operation.
V cable supplier: What should be noted when using control cables?
Control cable overview Cables that connect from the control center to various systems to transmit signals or control operational functions are collectively referred to as control cables. The early functions of control cables were relatively simple, including: indicator display, appearance indication, operation of relays and switching devices, alarm interlocking systems, etc. In recent years, due to the widespread application of weak electricity and computer networks, higher functional and application requirements have been put forward for the selection and application of control cables.
Main control cable series, the main products of control cables now include: polyvinyl chloride insulated control cables, natural butadiene rubber insulated control cables, and polyethylene insulated control cables. In addition, there are cross-linked polyethylene insulated and ethylene propylene rubber insulated products. Currently, China can also produce 600/1000 volt plastic insulated control cables.
Methods to ensure the normal operation of control cables and avoid interference. To ensure that control cables can reduce the damage range of insulation breakdown, mechanical damage, or fire, for two systems that require improved reliability, such as current, voltage, DC power supply, and trip control circuits, dual maintenance should use separate control cables.
