Antun Antun wire and cable wire and cable _ Which product is suitable for rated voltage 500V and below a higher anti-interference requirements computer and automation connectivity cable. Ground cable core computer cables computer cables must edge using K-type class B with antioxidant properties of low density polyethylene. Polyethylene insulation resistance of a high withstand voltage is good, a small dielectric constant and temperature and variable frequency of loss of influence is small, not only to meet the transmission performance requirements, but also to ensure that the cable life. 1 [1] In order to reduce crosstalk and external interference between circuits, shielded cable structure. Cable shielding requirements are based on different occasions were used: combination of shielded twisted pair, shielded twisted pair cables composed of the total, after combination of shielded twisted shield other methods. Shielding materials are round copper wire, copper, aluminum / plastic composite tape of three. Shield with the shield has good insulation properties of the cable in use shield, if shield potential difference between the pair, will not affect the signal transmission quality. Laying temperature not lower than: fixed laying -40 ℃, non-fixed laying -15 ℃ minimum bending radius: non-armored cable should be not less than 6 times the outer diameter of the cable with armored cable diameter should be not less than 12 times at 20 ℃ stability test charging voltage DC 500V 1min insulation resistance should be not less than 2500MΩ · Km between each pair shielded twisted and shielded twisted pairs and overall shield should continue the way of the cable core and the core of shall be subjected to between room and a shield 50HZ, AC 2000V voltage test 5min without breakdown Hefei Power Cable Co., Ltd ||| Antun Antun Antun wire and cable wire and cable _ Which is good
