Intrinsically safe signal cable

Dielectric coefficient is small and medium loss temperature and variable frequency of loss of influence is small, not only to meet the transmission performance requirements, and can ensure the service life of the cable shield material for round copper wire, copper, aluminum / plastic composite tape of three. The shielding pair has better insulating performance with the shield, and if the cable is in use, if the potential difference between the shielding pair occurs, the transmission quality of the signal can not be affected.

Long term operating temperature of the cable conductor: polyvinyl chloride has 70 degrees Celsius, 105 degrees Celsius, two kinds of polyethylene insulation for 70 degrees C; crosslinked PVC insulation for 90.

Semi flexible cable widely used in microwave communications industry in the mobile communication industry, with excellent RF transmission performance and power capacity, is a substitute for semi-rigid radio-frequency cable of the main products, at present in the domestic and international has formed scale production. China's semi soft coaxial communication cables before the market is mainly the monopoly of foreign cable companies, but with the rise of domestic enterprises, has been part of the enterprise, through the absorption of foreign advanced design ideas to independent research and development of innovative, successful research and manufacturing the worthy comparable with foreign products of semi soft cable product, not only to replace the import, but also a large number of exports.

With the increasing domestic market and the gradual improvement of the quality of domestic products, the development of China's independent intellectual property rights of the communication cable international standard is increasingly urgent. "This is the first time in our country to develop communication cable international standards, the whole process is not easy, we are through repeated communication, negotiation, and finally achieve zero breakthrough." IA-JYPVP22- intrinsically safe signal cable

Shielded control cable from the insulated wire core directly into the cable, the general shield, the computer cable in accordance with the needs of the general use of insulated wire core against the twisted or total shielding, or sub shielding + total shield.

Computer cables for rated voltage 500V and below for anti interference requirements of the higher electronic computer [1] 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.
