Product Identification

01 Cores of Cable Wire

Color mark 1 core: omit 3 core: red, yellow, green (plus color tape)

02 Teacă

The outer sheath of the cable is usually black, but other colors can also be used in accordance with the manufacturer or buyer’s agreement to adapt to its use environment. The cable should have a continuous identification of the manufacturer’s name, product model, rated voltage, and the manufacturer’s name identification can be a repeated identification of the manufacturer or trademark. The distance between the end of a complete mark and the beginning of the next mark: should not exceed 500mm on the cable outer sheath; The cable insulation or tape should not exceed 200mm. Printed signs should be rub resistant and not easy to fall off, and the print on the surface should be legible.

Note: The mark on the surface of the sheath can also add other content according to the custom of the user or the manufacturer.

Delivery and Tolerance

01 Delivery Length

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

02 Length Error

The measurement error of delivery length is ±0.5%.

Packaging, Transportation and Storage

01 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.

02 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.

03 Storage

The finished cable 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.

Order Instructions

When ordering, the cable model, specification, length, delivery date, packing method and other necessary information should be correctly marked. For example:

Model: YJV

Specification: 3×150

Length: 200m

Packing method: iron tray packing

Delivery date: last day valid

Mode of transport: train transport, car transport, ship transport or air transport
