Shanghai factory BVVB flat cable instruments and meters, power cable

Product Description:

Specifications: BVVB

Voltage levels: 300/500 v

Execution standard: JB/T8734-2012

Scope of application: this product is used ac rated voltage up to and including 450/750 (U0 / U) power, electrical appliances, instrumentation and telecommunications equipment.

Using features: 1, the cable of rated voltage U0 / U for 300/500 v. 2, long-term allowed working temperature does not exceed 70 ℃. More than 3, short circuit temperature: cable or multicore cable short circuit occurs (the longest duration of no more than 5 s), the highest temperature conductor does not exceed 160 ℃. 4, installing a wire laying, bending radius should be greater than the specified value. Diameter greater than 25 mm above the wires, bending radius should not less than 6 times of cable diameter. Diameter is less than 25 mm below the wire, bending radius should not less than 4 times of wire diameter. 5, PVC insulated and sheathed wire and cable laying, environment temperature should not be below 0 ℃. 6, plastic insulated wire such as BV cloth when installing laying wires, if wear pipe laying, should give full consideration to the diameter of the plastic pipe size, pipe threading the total cross section should be not more than 40% of the plastic tube hole section, for the normal operation of electric wire have plenty of room cooling, installation and wire laying should be far away from heat source.

Key performance indicators: 1, the conductor when 20 ℃ maximum dc resistance, 24.5 Ω/km. 2, the ac voltage 2500 v, 5 minutes not breakdown.
