HEINE's tubular resistors are available as single-tube, double-tube and multi-tube resistors, demonstrating the flexibility of this highly durable product range. Resistance coils – which can also be designed to be low-inductance – are attached to ceramic tubes of various diameters. Clips that also act as electrical connections are used for securing the resistance wire at either end of the coil.

What makes HEINE frame resistors so special is their compact and modular design. Low inductivity and high insulation voltage are ensured by means of frames made from electrically insulating or metallic materials. Even if the resistor wire heats up, it remains firmly supported and fixed.

Both types can also be used with thermal monitoring. Wire resistors are used mainly as braking and chopper resistors, charging/discharging/damping resistors and testing resistors.
