Aluminum Encased Power Resistors
(AL)Power Low Profile Aluminum Encased Resistors (AL) Preview
Token's flat core winding technology allows for wirewound heatsinkable aluminum housed wirewound resistors affording a very low profile, and superior thermal transfer characteristics when compared to conventional power wirewound resistors.
AL Low Profile Aluminum Encased Series is durable, vibration-proof, dissipates heat well and low temperature coefficient with resistance varying in direct proportion.
The product is easy to utilize and install, and suitable for a wide range applications. Applications include industrial machinery, load testing, electric power distribution, instruments, and automated control installations.
The AL Series is RoHS compliant and lead free. For non-standard technical requirements and custom special applications, please contact us to discuss the details.
Construction :
- An aluminum encased consists of an alloy metal coil-type resistance element assembled into an aluminum enclosure.
- After high-temperature anodization, the enclosure is filled with a special non-flammable cement paste and hardening.
- Insulation is applied through a high-temperature process.
- Since this component is embedded in the heat-proof cement, it is not affected by external mechanical force, and dusty environments.
