Twisted pair computer cable

Product Name: Copper Core Polyethylene（PE）Insulated twisted pair shielded cable for electronic computers

● Product model:DJYVP | DJYVP2 | DJYVP3 | DJYPV | DJYP2V | DJYP3V

● Execution standards:This product follows the enterprise standard and adopts the UK as a referenceBS5308Standards and JapanJCS189Standard manufacturing.

● Product Usage:

This product is suitable for connecting basic devices and instruments with high anti-interference performance requirements in electronic computer networks and control systems. Used for rated voltage500VCables for electronic computers and automation connections with high anti-interference requirements. The insulation of the cable ground wire core is made of materials with anti-oxidation propertiesKtypeBLow density polyethylene. Polyethylene has high insulation resistance, good voltage resistance, low dielectric constant, and minimal temperature and frequency effects on dielectric loss. It not only meets the requirements of transmission performance, but also ensures the service life of cables.

In order to reduce mutual crosstalk and external interference between circuits, the cable adopts a shielding structure. The shielding requirements for cables are based on different occasions, using methods such as twisted pair combination shielding, total shielding of twisted pair cables, and total shielding after twisted pair combination shielding.

Shielding materials include round copper wire, copper strip, and aluminum strip/There are three types of plastic composite tapes. Shielding pairs have good insulation performance, and if there is a potential difference between shielding pairs during cable use, it will not affect the quality of signal transmission.

Product model, specifications, and scope of use:（Note: Flame retardant cables should be added before the model number“ZR”； Fire resistant type“NH”）
