Ceramic wire-wound resistors

High quality wire wound on ceramic core

DESCRIPTION

Ceramic wire-wound resistors consist of a resistance wire wound around a ceramic core. The shape of the resistor can be round or oval and is coated with an insulating material.
The ceramic resistors comply of one or multiple ceramic wire-wound resistors fitted with a protection grid and optional connection box and or thermal switch. We produce ceramic wire-wound resistors only to costumer's drawing, sample and to costumer's requirements.

APPLICATIONS

  • Brake resistors
  • "Snubbers" (attenuators in controlled and uncontrolled rectifiers)
  • Charging and discharging resistors
  • Starting of large electric motors
