2000W Aluminum Housed Wirewound Power Dynamic Snubber Resistors
Structure :
1.The resistors core components are made of insulating and
high-temperature resistant materials as the resistors
framework,evenly wound with high-quality alloy wires.
2.Metal aluminum shell potted with high insulation non-combustible
electronic paste,so that the aluminum shell and the resistance core
components are closely combined into a solid entity,not affected by
external air,vibration and dust,high stability and thermal
conductivity.
3.ZENITHSUN series including ASZ(trapezium shape),ASC (ship
shape)and ASCB(ultra-thin shape),the mould can get more than 20
species to let resistors suit for environment installation and
application. Aluminum housed resistor is also called braking resistor or
charge resistor or bleeder resistor or current-limited resistor or
ageing resistor or load resistor.Resistance to shock,strength power
,fast dissipation heat ,high stability,long life.Aluminum resistor
is one of core products of ZENITHSUN.ZENITHSUN is the most complete
varieties and most powerful production aluminum resistors of
manufacturer in Pearl River Delta,and even in the whole country of
China.
