NSPV Weather Protected AC Isolating Switches The IP66 Weatherprotected Isolating Switches is a robust range of switches suitable for virtually any external application. Fixed Earth and Neutral connector bars with dual clamping screws per tunnel provide equal stripping lengths and secureclamping for all cables. Terminal bore size is 5 x 6.6mm. Included in the range are 1,2, 3 and 4 pole switches from 20 to 80 Amps. And the colour include white and grey.The basemounted mechanism provides for easier termination and more wiring room. Switch dimensions are 165mm x 82mm with anoverall height of 85mm. A safety feature for mounting switches to metal structures is the insulating caps that cover base mounting screws to totallyprotect them from any live cables. Dual 25mm screwed conduit entries top and bottom (up to 55 amp.) allows four ways to surface wire the switch. 55 amp.and above are also available with 32mm entries top and bottom.

Silicon nitride magnetic rings are mainly used to protect high voltage electrodes and are widely used in the photovoltaic industry.Heat shields and magnetic rings, as well as ceramic rings, are collectively referred to as electrode shields.Silicon nitride electrode protection cover mainly uses silicon nitride insulation, heat resistance and corrosion resistance.Compared with the protective cover of quartz and alumina which is still in use today, the service life of the silicon nitride electrode shield is more than 10 times, and it will not be electrically broken down during use, and will not be heated, nor will it be heated. Will be eroded away. Due to its own stability, in the use of photovoltaic reduction furnaces, the collapse rate of non-human factors is greatly reduced.
