Product Identification
Core of cable
Color identification of 2-core cables：No preference for chromatography；3-core cable: green/yellow, light blue, brown or light blue, black, brown; 4-core cable: green/yellow, light blue, black, brown or light blue, black, brown, black or brown; 5-core cable: green/yellow, light blue, black, brown, black or brown, or light blue, black, brown, black or brown, black or brown.
Sheath
The outer sheath of the cable is usually black, but colors other than black may also be used in accordance with manufacturer or buyer agreement to suit the environment in which they are used. Cables should have continuous identification of the manufacturer’s name, product model and rated voltage. The manufacturer’s name identification can be a repeated identification of the manufacturer or trademark；The distance between the end of one complete mark and the beginning of the next mark: should not exceed 550mm on the cable outer sheath；The cable insulation or tape should not exceed 275mm; The printed logo should be scratch-resistant and not easy to fall off, and the printed content on the surface should be clearly legible. Notice：the logo on the surface of the sheath can also add other logo contents according to the habits of the user or manufacturer.
Delivery and Tolerance
Delivery Length
The length of a reel of cable is 100m, the length of each roll is 100m, and the length of each cable drum should be greater than 100m. Alternatively, cable laying of any length may be allowed upon mutual agreement.
Delivery and Tolerance
Delivery length measurement error is ±0.5%
Packaging, Transportation and Storage
Packaging
Cables in rolls or coils should be neatly wound and properly packed. The cable tray shall comply with JB/T 8137-1999. The cable ends should be securely sealed. The cable ends extending out of the disk should be covered with a protective cover. The length of the cable ends extending out of the disk should be less than 300mm. The cable package shall bear a label indicating: Manufacturer name, model, specification, rated voltage, length, quality, manufacturing date, standard number or certification mark, the correct rotation direction of the cable tray, etc.
Transportation
Transportation is generally in the form of vehicles and ships, and the cable must be firmly fixed during transportation to avoid mutual collision or tipping over and causing damage to the cable or equipment. Cable tray is not allowed to lay flat. It is strictly forbidden to drop the cable tray with the cable from the height during transportation.
Storage
The finished cable should be stored in an environment where the temperature is between 5 and 35 ° C and the humidity is below 85%, so that it is not directly exposed to sunlight or rain, and it should be properly ventilated to keep the environment dry；They are out of touch with acids, alkalis, mineral oils
Order Instructions
When ordering, the cable model, specification, length, delivery date, packing method and other necessary information should be correctly marked.
Installation Notice
During installation, the ambient temperature should not be lower than -10°C. If the ambient temperature measured by the thermometer is lower than 0°C, preheat the cable before preparing for installation. The bending radius of multi-core cables shall not exceed 10D (D is the outer diameter of the cable) to avoid mechanical damage to the cable interior.
