How to choose high-quality cables
Cables play a vital role in power transmission, communication and other transmission applications. Choosing the right cable is not only related to the normal operation of the system, but also directly affects the safety of people and property.
Here are some basic points for selecting high-quality cables:
▶Certification mark
Confirm the "CCC" certification: All legitimate cable manufacturers must pass the "CCC" certification of the China Electrical Product Certification Committee and clearly mark this certification mark on their products.
▶Inspection report
Request for quality inspection report: Regular manufacturers regularly accept quality inspections by the supervision department, so when purchasing, you should ask the merchant to provide the latest quality inspection report to ensure the quality of the cable.
▶Packaging quality
Pay attention to packaging details: The cable products of regular enterprises are exquisitely packaged, with clear and complete labels, including information such as the manufacturer's name, address, model specifications, etc.
▶Appearance quality
Observe the surface state: High-quality cables have a smooth and flat appearance and uniform color. In particular, rubber insulated soft cables should have good roundness and hardness, and are not easy to be manually stripped.
▶Conductor quality
Check the conductor characteristics: Whether it is aluminum or copper conductors, they should be glossy and free of oil stains. Its DC resistance value should meet national standards to ensure good conductivity.
▶Length measurement
Verify the cable length: The standard length is 100 meters ± 0.5 meters. When purchasing, pay attention to whether the actual length meets the standard requirements to avoid purchasing short-length cables.
▶Classification and application
Choose appropriate cable types according to different usage scenarios, such as power cables, control cables, communication cables, etc., and pay attention to their applicable conditions and environmental requirements.
Installation precautions
▶Professional installation: The installation of cables should be completed by technicians with corresponding qualifications.
Ambient temperature: The ambient temperature should be considered during installation, especially under low temperature conditions, plastic insulated cables may require preheating.
Protective measures: Avoid physical damage to the cable during installation, and plan the cable path reasonably to avoid high temperature sources and corrosive substances.
▶Storage and transportation
Proper storage: The cable should be stored in a dry and ventilated place and kept vertical to prevent moisture intrusion and internal aging.
Professional handling: During transportation, appropriate tools such as cranes should be used to move the cable reel to avoid damage caused by rolling directly from the vehicle.
