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.

Aluminum nitride ceramics have excellent electrical and thermal properties, and are considered to be the most promising high thermal conductivity ceramic substrate materials. In order to seal the package structure, mount components and connect input and output terminals, the surface and interior of the aluminum nitride ceramic substrate need to be metallized. The reliability and performance of ceramic surface metallization have an important impact on the application of ceramic substrates, and firm bonding strength and excellent air tightness are the most basic requirements. Considering the heat dissipation of the substrate, it is also required to have high thermal conductivity at the interface between the metal and the ceramic. The metallization methods on the surface of aluminum nitride ceramics include: thin film method, thick film method, high melting point metallization method, electroless plating method, direct copper cladding method (DBC), etc.
