1000W High Power Aluminum Enclosure Braking Resistor For Inverter
Structure
1.An aluminum encased consists of an alloy metal coil-type resistance element assembled into an aluminum enclosure.
2.Following high-temperature anodization,the enclosure is filled with a special non-flammable cement paste and after hardening,insulation is applied through a high temperature process.
3.Since this component is embedded in the heat-proof cement,it is not affected by external mechanical force,and dusty environments.
Features
1.Durable,vibration-proof,dissipates heat well and low temperature coefficient with resistance varying in direct proportion.
2.ASZ series successfully applied for national patent (ZL2004300866567)
