Cement Resistor Ceramic Case 95% Alumina High Dielectric Strength Wirewound Resistor Ceramic Shell

Cement resistor ceramic case is a key insulating ceramic component for encapsulated wirewound cement resistors. Adopting 95% /99% alumina ceramic raw material, this ceramic shell owns high dielectric strength, low thermal expansion coefficient and excellent heat shock resistance. It can isolate the resistance wire and avoid short circuit, fire risk under continuous high-load working condition.

✅ High insulation & high dielectric strength ✅ Excellent high temperature resistance, non-flammable ✅ Good thermal dissipation, stable in harsh working environment ✅ Low water absorption, moisture-proof & corrosion resistant ✅ Customizable shape, size, tolerance per customer specification ✅ Strict dimensional tolerance, suitable for automatic assembly

• 95 Alumina Ceramic (95% Al₂O₃, cost-effective, mainstream choice)
• 99 Alumina Ceramic (99% Al₂O₃, higher insulation & thermal performance)

Widely used in cement wirewound power resistors, braking resistors, load resistors for power supply, frequency converter, inverter, industrial automation, elevator, new energy equipment.
