Common cable model YJV22 cable brief

YJV22 is an armored steel tape copper core cable, the full name is: copper core cross-linked polyethylene insulated PVC sheathed steel tape armored power cable; Where YJ represents cross-linked polyethylene, V represents polyvinyl chloride lining, which can be extruded or wrapped, 2 represents steel tape armor, and 2 represents polyvinyl chloride outer sheath.

YJV22 cable is a kind of double layer steel tape armored low voltage cable. It is in the conductor and insulation layer, and then put on a layer of steel tape armor, increase the mechanical protection performance of the cable. The conductor of YJV22 cable uses copper core as the YJV cable, and the insulation material is also cross-linked polyethylene, but a layer of steel strip is added to the sheath layer. This makes YJV22 cable more suitable for some harsh environments, such as high temperature, high humidity, easy to pressure and impact and other occasions. Its sheath material can be effectively waterproof, moisture-proof, oil-resistant corrosion, etc., and has a wider range of applications.

In fact, YJV22 is the armored copper core cable that we can often see, and the YJV armored cable is divided into steel tape armored (YJV22/23), thick steel wire armored (YJV42/43) and fine steel wire armored (YJV32/33).

YJV22 cable is also subdivided into categories: flame retardant ZR-YJV22 cable, fire-resistant NH-YJV22 cable, low smoke halogen-free WD-YJV22 cable, low smoke halogen-free fire-resistant WDN-YJV22 cable, low smoke halogen-free flame retardant WDZ-YJV22 cable, low smoke halogen-free flame retardant fire-resistant WDZN-YJV22 cable, etc.

Specifications of YJV22 cable:

1. Number of YJV22 cable cores: 1 core, 2 core, 3 core, 4 core, 5 core, 3 1 core, 3 2 core and 4 1 core.

2. YJV22 cable cross-sectional area: 2.5mm, 4mm, 6mm, 10mm, 16mm, 25mm, 35mm, 50mm, 70mm, 95mm, 120mm, 150mm, 185mm, 240mm, 300mm, 400mm

The use of YJV22 cable characteristics:

1. The long-term allowable working temperature of the cable conductor is more than 70 ℃.

2. The maximum temperature of the cable conductor shall not exceed 165 ℃ during short circuit (the longest duration shall not exceed 5 seconds).

3. The cable is not limited by the laying drop, and the ambient temperature during cable laying shall not be lower than 0 ℃.

4, good chemical stability, acid, alkali, salt, oil and organic solvents, and has the characteristics of flame resistance.

5. Light weight, good bending performance, simple installation and maintenance.
