Identification of product

Wire core

color spectrum：The preferred chromatogram for cables is two core’s cable, Sin preferencia por la cromatografía。Three-core cable: yellow/green, azul claro, marrón, o azul claro, negro, marrón. Four-core cable: yellow/green, azul claro, negro, marrón, o azul claro, negro, marrón, negro o marrón. Five-core cable: yellow/green, azul claro, negro, marrón, negro o marrón, o azul claro, negro, marrón, negro o marrón, negro o marrón, (Tip: Manufacturers can edit the color spectrum according to actual conditions)

digital identification: When the insulated core is marked with a number, Insulation should be of the same color and arranged numerically, except for yellow/green combination color insulated cores

Numbers apply Arabic numerals printed on the surface of the insulated core, The color of the numbers should be the same and clearly contrast with the insulation color and the writing should be clear,

The numerical designation shall be repeated at equal intervals along the insulated core Two adjacent sets of numerical signs should be reversed. When the flag consists of a single number, then you should put a dash below the number. If the flag consists of two numbers, then they should be arranged up and down and a dash should be placed under the following numbers. The distance between two adjacent sets of digital signs should not be greater than 50mm.

Vaina

Cables shall be continuously identified with the manufacturer’s name, Modelo de producto y voltaje nominal, The logo of factory’s name can be a duplicate of the manufacturer or repetitive identification.

The distance between the end of one complete sign and the beginning of the next sign The outer sheath of the cable should not exceed 550mm The cable insulation or tape should not exceed 275mm; The printed mark should be erasure resistant and not easy to fall off, and the printed content on the surface should be clear and recognizable

Delivery of goods and the length of the differences

Delivery of length

The length of the circle should be 100m, and the length of the disk should be greater than 100m. 24 cores and below : Short cable lengths of not less than 20 meters are allowed for delivery, The delivery length of the short section cable should not exceed 5% of the total delivery length. 24 cores or more: Short cable lengths of not less than 20 meters are allowed for delivery, The delivery length of the short section cable should not exceed 10% of the total delivery length. Or it can be delivered in any length according to mutual agreement

Error in length

The measurement error of delivery length should not exceed ±0.5%.

Embalaje, transportation and storage

Embalaje

1、Cable in rolls or coils is orderly winding and properly packed

2、The reel of cable shall comply with JB/T8137-2013,The end of cable should be reliably sealed, The cable ends extending out of the reel should be protected by a protective cover.

3、The package of cable should be attached with a label indicating: manufacturer name, modelo, especificación, Voltaje nominal, largura, calidad, Fecha de fabricación, Número estándar o marca de certificación, correct rotation direction of the cable drum, etcetera.

transportation

Transportation generally takes the form of vehicles or ships. During transportation, the cables must be firmly fixed to avoid damage to the cables or disks due to collision or overturning.

storage

Finished cables should be stored in an environment with a temperature between 0 y 40 degrees Celsius and a humidity below 85%. They should not be exposed to direct sunlight or rain. They should be properly ventilated to keep the environment dry. Cables should be stored and used in accordance with the above regulations and can generally be used for more than 25 years.

Ordering matters

Necessary information of ordering such as cable model, especificación, largura, packaging method, date of delivery, etcetera. should be correctly indicated.

For example

Model of cable：KVVP-(R)-0.45/0.75kV

especificación：24×1.5

largura：10000m

packaging method： Iron plate packaging

date of delivery：Validity period days

Instructions of Installation

Durante la instalación, the ambient temperature should not be lower than 0°C. Si la temperatura ambiente medida por el termómetro es inferior a 0 °C, the cable should be preheated before installation. The bending radius during cable laying should be strictly controlled

In order to avoid mechanical damage inside the cable。The yellow/green double-color insulated wire cores should be connected according to the designated positions.
