MAIN TECHNICAL PARAMETERS

Note: when the product is used at an altitude of more than 1000m, the insulation level is carried out according to the corresponding correction factor.

Product features

1, miniature vacuum arc extinguishing chamber:The maximum reliability, long working life, encapsulated in solid sealed pole (solid).
2, solid sealing pole:In line with environmental protection requirements, has been widely validated outdoor performance, resistance to ozone and ultraviolet, fastening, light, not easy to crack, easy to transport.
3, the design structure is reasonable:Sealed pole support insulator, the upper part of the sealed pole, the lower support insulator, with insulating rod and long rod, three-phase support insulator mounted on a common mechanism box, interrupter moving through the output end of the pull rod and the mechanism of the shaft is connected with the moving end of the vacuum interrupter.The connecting rod is connected with the output shaft of the mechanism to move directly to the mechanism output shaft. Safe and reliable, and maintenance of edge.
4, with automatic distribution interfaceCan be flexible with sports auxiliary contacts, to meet the requirements of distribution automation.
5, high parameters, high performance:Rated current can reach 2000A, rated short circuit breaking current is 31.5kA.
