Product identification.

Core of cable

Color mark 1 core: Omit, 3 core: red, yellow, green (color stripe)

Sheath

The outer sheath of the cable is usually black, but a color other than black also can be used in accordance with the manufacturer or buyer’s agreement to adapt to its use environment. The cable shall have continuous identification of the manufacturer’s name, product model and rated voltage, and the manufacturer’s name identification may be repeated identification of the manufacturer or trademark; The distance between the end of one complete mark and the beginning of the next mark: shall not exceed 500mm on the outer sheath of the cable; on the cable insulation or tape should not exceed 200mm. The printed logo should be erasable and not fall off, and the printed content on the cable should be legible. Note: The logo on the sheath can also add other content according to the custom of the user or the manufacturer.

Delivery and tolerance.

Delivery length

Cables weighing less than 80kg are allowed to be delivered in circles, if there is no agreement, the delivery length is not less than 100 meters. It is permitted that the length of the short cable is not less than 20 meters, and the quantity of the cable does not exceed 10% of the total length of the delivery, or any length of cable may be delivered according to mutual agreement.

Length error

Delivery length measurement error is ±0.5%.

Packaging, transportation and storage.

Package

Cables in rolls or coils should be wind in order and properly packed. The cable drum shall comply with JB/T 8137-1999. The cable ends should be securely sealed. The cable ends extending out of the drum should be covered with a protective cover. The length of the cable ends extending out of the drum should be less than 300mm. The cable package should be labeled with: manufacturer’s name, model, specification, rated voltage, length, quality, manufacturing date, standard number or certification mark, the correct rotation direction of the cable drum, etc.

Transport

Transportation is generally in the form of vehicles and ships, and the cable must be firmly fixed during transportation to avoid bumping or tipping over to cause damage to the cable or disc. Do not lay the cable drum flat. It is strictly forbidden to drop the cable tray containing the cable from a height during transportation.

Storage

Cables should be stored in an environment where the temperature is between 0 and 40 ° 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. Cables are stored and used in accordance with the above requirements and can generally be used for more than 25 years.
