Non - metallic conduits and fittings for electrical installations - pliable corrugated , plain and reinforced conduits of self - extinguishing plastics material
4.
Feature : self - extinguishing and anti - static . belt strength , elongation , troughability and flexibility can be selected according to different kind of carcass for requirements of different service conditions
5.
Low viscosity , self - extinguishing rtv silicone compound , used in situations where component identification and vibration shock protection is needed , the transparency permits visual inspection for easy identification and repair of encapsulated parts
6.
The blasting circuit breaker and the studied self - extinguishing circuit breaker that are in the same voltage level are compared . it proves that the arc energy can be used to help build the pressure of the expansion chamber and extinguishing the arc in order to lessen the driven energy
7.
In this paper , the gas flow is simulated in the 252kv self - extinguishing type sf6 circuit breaker which is being studied by the tianying company in pingdingshan . the idea which combines the self - programmed method and the fluid computation software is presented
8.
The paper calculates and analyzes the influences of the initial pressure , the volume of the expansion chamber , and the throat diameter of the nozzle on the non - loaded performance of the circuit breaker , and presents the variation of the state parameters of the expansion volume and the flow field during interruption period , also predicts the nature of the self - extinguishing circuit breaker
