Wire-wound resistors are mainly used for applications in the lower load range up to several kilowatts at low current and/or higher ohm values.

Systems

Tube resistors
Tube resistors consist of a wire wound on a ceramic carrier tube. GINO manufactures mainly tube resistors with concrete-coated winding. The concrete coat is annealed in an oven after application and drying which gives a high strength and excellent resistance against high moisture.

Siemens 3PP1 resistors
Are air-cooled resistors with cylinder resistors 3PY6. The compact design is particularly suited for intermittent operation in many applications (starting resistors, excitation resistors and field discharge resistors in magnetic control units, braking resistors).

In 1999 GINO took over the production of all Siemens-Resistor-Systems as well as the production of cylinder resistors 3PY600.. and 3PP13.

Wire-wound frames
Are flat elements with wire windings on ceramic supports at the top and bottom of a carrier frame. The ceramic supports are provided with groves to take on the wire. For ceramic supports without groves, the windings have to be fixed with concrete coating like with the PZ. Due to the uniform design, wire-wound frames are equally suited as system resistors. With a similar design to GINO steel grid resistors, GINO wire-wound frames can be combined with each other and with the steel grid resistors. In this context, a wire-wound frame takes the place of two steel grids.

Wire grids, system AEG
Are system elements that match the AEG cast iron resistor system. The elements are resistant to breaking and exhibit a lower temperature coefficient of the electrical resistor than cast iron elements.

Vitreous enameled resistors
Are wire-wound resistors on ceramic tubes whose windings are then coated in a baking oven with a glazing that affords protection against environmental effects.

Encapsulated resistors
Are encapsulated resistors in an aluminum casing with high protection class and non-detachable connection lines, mainly designed for applications requiring high overload capacity and a high protection class.

Standards

The resistor wires used comply with the specifications of DIN 17471, whereby separate standards apply for the alloys. They meet the applicable regulations VDE 0100 and VDE 0660 and conform to the EEC Low Voltage Directive dated 19 February 1973.
