Shielding Cable for Computer Application ( Cable for DCSSystem Application

Shielding Cable for Computer Application ( Cable for DCSSystem Application

1.Scope ofapplication

lt is used as connection cable of inspection devices and instrumentswith high demand on interference resis tant performance in computernetwork and control sys- tem.

2.Executive standard:

TICW/06-2009 or BS5308 standard for reference

3.Performance for Usage

1: AC rated voltageU./U: 300/500V. Long term work- ing temperatureof cable conductor is 70℃ & 105℃ for cable with PVC insulation,70℃ for cable with PE insula-tion and 90℃ for cable with XLPEinsulation.(XLPE insu- lation includes silane XLPE & irradiationXLPE insulation.)

2: Min. environment temperature is -40℃ for fixed laying and-15℃for non-fixed laying. Environment tem-perature shall be no lessthan 0℃ for installing.

3: Min.bending radius allowed by cable is no less than 6 timesthat of cable OD for non-armored soft cable or braided shieldingcable and 12 times that of cable OD for cable with metallic tapewrapped shielding or steel wire/steel tape armor.
