Details of the computer cable

This product is suitable for the exchange of U0 / U 300/500V power, metallurgy, petrochemical and other industries to computer-based automatic control systems, Distributed Control System automation and control systems for the line of control and detection instrumentation computer cable.
The performance of the computer cable

① ???? Wire core insulation material with excellent antioxidant and anti-aging properties of PE plastic, of XLPE plastic or PVC plastic, insulation resistance, voltage ?? The high dielectric constant and dielectric loss is small, the small influence of temperature and frequency, to meet the transmission performance, the normal life of the cable length.

② ???? In order to reduce the line between the signal crosstalk and outside interference, cable multi-shielded structure. The use of different occasions and different shielding methods, group shield, or into three total shielding, or group in the cable shield bonus cable shield. Shielding materials have copper wire (P), Copperbelt _(2), aluminum-plastic composite tape ₍₃₎ three.

③ ???? Good insulation between the shield and the shield, if the cable between the use of shielding potential difference, it will not affect the transmission of data signals and quality.

④ ???? Polyethylene insulation and PVC insulated cables for long-term allowable working temperature does not exceed 70 ° C, XLPE insulated cable is long-term allowable working temperature does not exceed 90 ℃.

⑤ ???? When the temperature of cable laying should not be less than 0 ° C below the temperature should be warm-up.

⑥ ???? Cable laying, bending radius:

- Armored shield cable, flexible cable shield should not be less than 6 times the cable diameter;

- Structure of armor or copper tape shield cable should not be less than 12 times the cable diameter;

⑦ ? Fixed laying the cable conductor with GB / T 3956-1997 1 round solid core conductor or two kinds of circular stranded conductors;

Moving installation of GB / T 3956-1997 of five kinds of soft and round stranded conductor flexible cable conductors.

⑧ ???? ? AC voltage test:

- Line the cores between the AC voltage to 1500V, 1min, cable breakdown;

- AC voltage is applied between the wire core and shielding 1000V, 1min, cable breakdown;

- Wire core + shield and armored AC voltage 500V, 1min, cable breakdown
