Trapezium Aluminum Housed Wire-wound Resistors is a kind of aluminum encased resistor that consists of an alloy metal coil-type resistance element assembled into an aluminum enclosure. Following high-temperature anodization, the enclosure is filled with a special non-flammable cement paste and after hardening, insulation isapplied through a high-tem perature process. Since the resistor is em-bedded in the heat-proofcement, is not affected by external me-chanical force, dusty environments, or extreme duty. It is durable and vibration-proof, dissipates heat well, and has a low temperature coefficient, with resistance varying in direct proportion.Supportingaflexible range of applications, the product is easy to utilize and install. Applications include industrial machinery, load testing, electric power distribution,instruments, and automated control installations. 

1. Aluminum housing surface with good performance in heat radiation,Suitable for cooling plate installation, Can be used in the atrocious environment.
2. Small size,High power load.
3. High insulating capacity,Encapsulation by non-flame inorganic material,Good performance in vibration.
4. Multi connection form will easy to utilize and install.
