Description
Specification:
1. The rat ED volt age of wires should equal to or higher than t rat ED volt age of the syst em when wires are used at AC system. If e wires are used at DC system, rat ED voltag e of sys tem should be lower than 1.5 times as high as r ated v oltage of cable and wires. The working voltage of syst em could be 1.1 times as high as the r ated volt age of cable.
2. The long term working temperature should lower then 70oC. The working temperature of BV-90 should lower then 90oC. And laying temperature should higher than 0oC.
3. The curve di am ete r of wire should longer than 8 times of iamet er of the outer diam et er of cable and wires if their outer diam ete r is 25 mm or above. If diameter of cable and wires is above 25 mm, curve diam e ter should be at least 12 times of outer dia meter of cable and wires.
4. Type and Laying place and requirement
Type Name Laying place and requirement Long term working Temperature 0C
