I. Brief Inntroduction of PC Cable

PC Cable applies to tamper-resistant electronic computer and automatic link cable for voltage 500V and below a higher requirement. Ground cable core insulation is used with anti-oxidant properties of K-B type low-density polyethylene. Polyethylene insulation resistance of a high withstand voltage is good, small and medium dielectric constant temperature and variable frequency of loss of influence is small, not only to meet the transmission performance requirements, but also to ensure the cable life.

In order to reduce the inter-loop crosstalk and external interference, PC cable uses shielded cable structure. Cable shielding requirements are based on different occasions when PC cables are used: combination of shielded twisted pair, twisted pair cables composed of the total shielding, shielded twisted pair combination of methods such as after the total shielding.

Shielding materials are round copper wire, copper strip, aluminum strip / plastic composite tape of three. Shield with the shield has good insulation properties of the cable in use of the shield, if shield potential difference between the right, it will not affect the signal transmission quality.

II. Technical Parameters of PC Cable

Product rated voltage (U0 / U): 300/500V

The long-term working temperature is 70 ℃

When laying the ambient temperature of not less than: fixed installation -40 ℃, non-fixed installation -15 ℃

Minimum bending radius: non-armor layer should be less than 6 times the cable diameter, with armored cable layer shall be not less than 12 times the cable diameter

At 20 ℃, Voltage 500V DC 1min test after the insulation resistance stability of charge should be no less than 2500MΩ • Km

As well as between the various pairs of twisted shielded twisted pair shielded with overall shield should be kept between the road

PC Cable and wire line core between the core and between the shield should be subjected 50HZ, AC 2000V breakdown voltage test is not 5min
