GINO Elektrotechnische Fabrik is a world-leading manufacturer of resistors for industry and traction applications. With plants in Germany (Bonn and Eisenach) and China (Shanghai) and representative offices in more than 15 countries worldwide, GINO supplies renowned clients with power resistors in the performance range from 50W to 360MW.

Traction resistors

Typical applications for our traction resistors are as follows:

  • Braking resistors
  • Damping resistors
  • Overvoltage limiter resistors (OVL, OVR, MUB and AZS)
  • Earthing resistors
  • Discharging resistors
  • Load resistors

Traction and trolleybus resistors

As a full-range producer we use several well-known resistor technologies and our own patented systems. The most widely used technologies for traction and trolleybus resistors are as follows.

Strip resistors or band resistors

Our strip resistors or band resistors can be comprised of two different systems, which are normally both made of a NiCr alloy sheet strip.

Braking resistor designed for mounting on the roof of the car body, with natural-air cooling.
This braking resistor is designed for mounting underneath the car body, featuring natural-air cooling.
Braking resistor with forced cooling by a high-performance axial fan, designed for mounting underneath the car body.
Tower resistor with forced cooling by a high-performance axial fan, designed for mounting inside a loco.
Our encapsulated resistors and compact resistors provide up to IP65 protection.

The 6GN1 system features punched and gilled strip elements connected in series by spot welding, mounted with ceramic insulators on support bolts provided with additional insulation.

The GINO-patented 3PQ4 system features continuously folded strips mounted between ceramic insulators on support bolts. Due to the high air and creepage distance, no additional insulation in the strip zone is required. Strip temperatures of up to 850°C are possible.

Wire-coil resistors

Wire coils resistors are normally made from NiCr-alloy welded onto terminal plates that are supported by ceramic insulators.

Encapsulated resistors or compact resistors

Our wire-wound encapsulated resistors or compact resistors, of VPR or DEG type, are embedded in a fully closed profile made of aluminium. Protection classes up to IP65 are possible.

Steel-grid resistors

Steel-grid resistors are comprised of steel-grid elements made of a NiCr alloy. All sizes and geometrics permitted by the material’s properties are possible. The elements are connected by screws or spot welding and mounted between ceramic insulators on support bolts.

All the resistor systems can be used for stand-alone resistors or can be mounted in a housing made of stainless steel, which is designed to meet each individual customer’s purposes.

Cooling for traction resistors

The best solution is to design the traction resistor in a way that natural cooling is sufficient. In this case the cooling of the resistor is caused by the natural convection of the air.

In other cases we use special blowers for traction applications to produce a forced cooling of the resistors.

We are specialists that can fulfil all your requirements. Ask us to design your specific power resistor.

IRIS-certified traction and power resistors

To supply the best quality is one of our biggest goals. We always keep our quality system up-to-date.

In autumn 2008 we were the first world-leading manufacturer of power resistors to successfully gain the new international traction-quality standard, IRIS. Other certifications we have achieved are:

  • ISO 9001:2008
  • DIN 6700-2
  • EN15085-2

Electrical power resistors

The roots and thus the experience of GINO in manufacturing of electrical power resistors go back to the beginning of the 20th century. The present GINO company was founded in 1977.

Train resistors

In 2000, GINO took over the industry and train resistor manufacturing activities of Siemens’ A+D PUIB department in Nuremberg, Germany, and with that the production and sales of all resistor products made by Siemens. These included cast-iron resistors, oil-cooled motor starters, motor starters, neutral-grounding resistors and resistors for traction applications.

Athens Metro

The Athens Metro in Greece is formed of an enlarged and upgraded suburban rail route, as well as two newer lines.

Docklands Light Railway Capacity Upgrade

Since opening in 1987, the Docklands Light Railway (DLR) has been central to the regeneration of east London. Now its significance is far greater than originally envisaged.

Amsterdam Metro / Light Rail Network by GVB

The largest single order for new-generation light rail vehicles was placed by the city of Amsterdam, Netherlands, as part of a major exercise to replace its antiquated fleet of 234 trams, which have become increasingly unreliable.

Guangzhou Metro

Guangzhou Metro is a light rail transit system in the city of Guanghzou (formerly known as Canton) in China. It is the fourth metro system to be introduced in Mainland China.

Thameslink Programme, London

The original Thameslink project led to through passenger trains being introduced on a core route between Bedford and Brighton via central London in 1988. Using the southern end of the Midland Main Line and the classic Brighton line south of Croydon, it was the first substantial service to pass through the capital, as opposed to enforced transfers for travellers between the termini established around the edge of central London by private companies in the mid-19th century.

Budapest Metro Four

The Municipality of Budapest and the State Government ordered the construction of a mass transit underground system in early 1998. The project was vigorously examined, and deemed to be the best answer to Budapest's increasing transport problems.

Houston MetroRail System

At present only a single line, the MetroRail operation of the Metropolitan Transit Authority of Harris County, (trading as METRO) is poised to become a comprehensive network.

Bremen Light Rail System

Bremen in north-west Germany is one of the two urban subdivisions, the other being Bremerhaven, that make up the country's smallest land (state), Freie Hansestadt Bremen.

Portland MAX Light Rail

Expansion of the Portland MAX (Metropolitan Area Express) light rail system continues apace. The next phase, due to open in 2009, will add a fourth route.
