1500V Cement Resistors High Temperature Non Inductive Wire Wound Resistor
Heating-type cement resistors are high-performance devices that integrate resistance and heating functions.
The products are made with highly stable resistance wire wound and encapsulated in a high-temperature resistant insulating cement shell, possessing excellent thermal conductivity and mechanical strength.
Their robust structure and uniform heat dissipation allow for long-term stable operation under high power loads and harsh environments.
The JRX series can be used for current limiting, voltage dividing, and as heating elements, and is widely applicable to industrial and household equipment.

The series utilizes a high-temperature sintering process and an inorganic insulation filling structure, resulting in excellent heat resistance and shock resistance. The resistor element can operate continuously in high-temperature environments without failure, ensuring long-term stable output.
The outer shell uses ceramic insulation material with an insulation resistance exceeding 10MΩ, effectively preventing leakage and short circuits. The internal design employs a high-temperature resistant iron cap and fiberglass skeleton, providing good mechanical strength and shock resistance.
The resistor wire structure is rationally designed, resulting in uniform heat distribution and stable temperature rise, suitable for both continuous heating and intermittent operation.
The series is widely used in electric heating devices, power supply equipment, household appliances, lighting systems, motor brakes, thermostats, and industrial instruments, among other fields. Its high temperature resistance, high stability and insulation properties make it an ideal choice for applications requiring current limiting, energy dissipation and thermal control.
