Customized Computer Cable - ngbengye - 03-26-2020
It is used to transmit automatic control signal in the environment not only with exploding danger such as petroleum, chemical plant, power, gas project and mine but also with high demand on explosion proof performance. It is decentralized type instrument signal cable with the feature of low capacitance & low inductance & good shielding performance and interference proof performance, which is also named as Intrinsic safety type cable for DCS system. So, its performance of explosion-proof & safety is apparently higher compared with common computer control cable and cable for DSC.
Executive standard: BS5308 standard for reference
Performance for Usage
1: AC rated voltageU0/U锛?00/500V.
2: Max temperature of cable conductor for long term working is 70鈩?for cable with PE insulation, 90鈩?for cable with XLPE insulation and 70鈩僨or cable with free halogen, low smoke, flame retardant, polyolefin insulation.
3: Min. environment temperature is -40鈩?for fixed laying and -15鈩?for non-fixed laying. Environment temperature for installing is no less than 0鈩?
4: Bending radius allowed by cable is no less than 6 times that of cable OD for inarmored braided shielding cable and 12 times that of cable OD for copper tape shielding, armored cable.
