INTRODUCTION

Cement resistors are manufactured by winding the ceramic rods with metal alloy resistance wire and put it in a fireproof ceramic box then concrete with non-flammable and heat-resistant cement.

Excellent heat resistance, low temperature coefficient of resistance and linear change.

It can withstand short-term overload, low noise, and the resistance value has not changed over the years.

Good explosion-proof performance and protection.
