Safe Use and Accident Prevention of Cable

Safe use and accident prevention of cables are important links that cannot be ignored in cable application. The following is an in-depth discussion of these two aspects:

Safe use of cables

Comply with product specifications: When using cables, you must strictly abide by the provisions of the product certificate, including input voltage, power and other requirements, and overload is strictly prohibited.

Attention to ambient temperature: During use, the temperature of the cable should not exceed the standard long-term allowable working temperature to prevent overheating of the cable from causing performance degradation or causing fire.

Correct connection and wiring: When connecting cables, pay attention to the correctness of phase color connection to avoid circuit failure caused by wrong connection. When routing cables, it is recommended to place them parallel to each other and ensure that the twist radius of the cable is greater than the corresponding radius of curvature to prevent excessive bending from damaging the cable insulation.

Prevention of mechanical damage: The cable should be protected from any mechanical damage during use, such as crushing, pulling, etc., and personnel are prohibited from walking on the cable.

Grounding protection: For cables with insulating layers, it should be ensured that the grounding is in good condition, and grounding protection is achieved through grounding wires and grounding devices to prevent accidents such as electric shock caused by electrostatic accumulation.

Accident Prevention of Cable

Prevention of overload operation: The rated current of the cable is determined by the manufacturer according to various factors, so attention should be paid to avoid overload operation when using it to prevent overheating or even fire of the cable.

Reasonable laying and protection: cable laying shall comply with relevant regulations, as far as possible away from heat sources, avoid parallel or cross arrangement with heat sources such as steam pipes, if it cannot be avoided, it shall maintain the specified distance and take insulation measures. In addition, cable tunnels should avoid joints, because the joint is prone to short-circuit failure, if it is necessary to install joints in the tunnel, the application of fire-resistant partition will be separated from other cables.

To prevent humidity: the cable will lose insulation performance in wet or immersed environment, so it is necessary to pay attention to moisture, waterproof, and regularly check whether the appearance of the cable has obvious changes.

Strengthen inspection and maintenance: formulate cable inspection system, inspect cable lines regularly, and timely discover and deal with possible external damage, corrosion and other problems. At the same time, the necessary maintenance and maintenance of the cable to ensure that it is in good working condition.

Use of safety equipment: In order to ensure the safe use of cables, necessary safety equipment, such as circuit breakers, fuses, grounding devices, etc., should be equipped to cut off the power supply in time when the cable fails to prevent the accident from expanding.

To sum up, the safe use and accident prevention of cables need to start from many aspects, including safe use measures such as complying with product specifications, paying attention to ambient temperature, correct connection and routing, preventing mechanical damage, grounding protection, and preventing overload, reasonable laying and protection, preventing humidity effects, strengthening inspections and maintenance, and using safety equipment. Through the implementation of these measures, it can ensure the safe and stable operation of cables and reduce the occurrence of accidents.
