This product is applicable to the rated voltage of 500V and the following requirements for anti interference of electronic computers and automatic connection cable. K type B low density polyethylene with anti oxidation property is used for cable wire core insulation. The insulation resistance of polyethylene is high, the resistance to voltage is good, the dielectric coefficient is small and the dielectric loss temperature and variable frequency influence is small, not only can meet the requirements of the transmission performance, but also can ensure the service life of the cable.
In order to reduce the mutual interference between the circuit and the external disturbance, the cable adopts the shield structure. The shielding requirement of the cable is to be used in different occasions, such as the combination of the twisted pair, the total shielding of the twisted pair and the total shielding of the twisted pair combination.
Shielding materials are round copper wire, copper strip, aluminum strip / plastic composite tape three. The shielding and shielding has good insulation properties of the cable in use if shielding on shielding potential difference between the right, will not affect the signal transmission quality.
The ambient temperature is not lower than the laying: fixed installation -40 C -15 C non fixed installation
Minimum bending radius: no armoring layer should be not less than 6 times of cable diameter, with armoured cable should not less than 12 times of cable diameter
At a temperature of 20 DEG C 500V DC voltage test stable charging 1min insulation resistance should not be less than 2500M - Km
Between each pair shield and to wring shielding and shielding should not break
Between the cable and cable and shielding should be subjected to 50HZ, 2000V AC voltage test 5min breakdown
