CM, CMW, the CME, the CMD busbar type wall bushing (high-voltage wall bushing)

CM, CMW, the CME, the CMD busbar type wall bushing (high-voltage wall bushing)
Product Detailed
1. rated voltage (10 ~ 35) kV 2. frequency (15 ~ 60) Hz 3. three phase

Product Description and Usage: An overview of the - CM, CMW, the CME, the CMD busbar type wall bushingHigh-voltage wall bushings: hereinafter referred to as the casing) to the rated voltage (10 ~ 35) kV, frequency (15 ~ 60) Hz three-phase AC system power station and substation power distribution unit, for the conductive part through the septum panels, walls or other grounded objects, since the insulation fixed connection between the support and the external conductor (busbar). Environmental conditions 1) households within the casingThe ambient temperature is not higher than +40 °C, not lower than -40 °CAn altitude of not more than l000mRelative humidity on average less than 90%Ambient air should not corrosive or flammable gas, water, steam, and so obviously dirtyRecurrent severe vibration 2) Outdoor casingThe ambient temperature is not higher than +40 °C, not lower than -40 °C;Elevation exceed l000m;Wind speed is not greater than 34m / sEnvironmental air contamination condition of use of the product, according to GB/T5582 divided into I, II, III, IV, 4;Recurrent severe vibration Second, product characteristicsCasing by the porcelain, metal accessories, the composition of the mounting flange and the conductive row (pole).Third, the use and classificationCeramic wall bushings for the power station and substation distribution equipment and high-voltage electrical appliances, for the wires through the ground partitions, walls, or electrical equipment enclosure to support the conductive part to make it right or housing insulation.

Ceramic wall bushings according to their use of the environment can be divided into indoor and outdoor ceramic wall bushings. Through the center of the conductor can be divided into the bus ceramic wall bushings, copper conductor, ceramic wall bushings and aluminum conductors, ceramic wall bushings.

When the copper conductor and the bus is directly connected, easy to produce galvanic corrosion, the contact surface temperature is too high cause the joints to burn, affecting the life of the equipment, it should be using copper and aluminum transition joints, but to cause trouble to the on-site construction, the use of aluminum conductors porcelain The casing can solve these problems.

Indoor and outdoor ceramic wall bushings porcelain pieces, conductive rod, both ends of metal accessories and mounting flange assembled. Bus ceramic wall bushings is made by the porcelain pieces, both ends of the metal accessories, bus plywood and mounting flange assembly (bus plywood usually with bus size by the user).

The performance of ceramic wall bushings in line with the provisions of the GB12944.1 voltage ceramic wall casing technical conditions.

CM, CMW, the CME, the CMD busbar type wall bushing (high-voltage wall bushing)
