Partnership for power

How has Weidmüller maintained such a strong relationship with the power industry for over 40 years? The partnership with power undoubtedly started with its "Klippon" terminals. From the early days of screw terminals and assembled enclosures, Weidmüller's portfolio has continuously been extended and improved. Today a wide range of Weidmüller products are being used in various types of power plants.

But operators' requirements don't just stop at the power plant. They also need products for transmissionand distribution systems, including sub-stations.

Weidmüller offers solutions and products for the following areas of the power industry:

Thermal power plants

• coal-fired power plant
• gas-fired power plant
• nuclear power plant

Renewable energy

• water power
• wind power
• photovoltaic
• biomass, biogas

Transmission and distribution

• switching technology
• network protection
• measurement technique

Starting at the coal-mill within a coal-fired plant over steam generation, generation of electrical energy trough the transmission and distribution of electrical energy, many of Weidmueller products are used. Weidmüller does offer a long-term and broad in-depth knowledge about the various fields of energy production. From standard terminals, innovative Push In technology over functional electronics with transducers, transmitters etc. and state of the art communication electronics for Industrial Ethernet, Bluetooth and others up to customer specific solutions and assemblies, we will find the right solution and product for your needs.

• Reliable surge protection

Lighting bolts and other voltage peaks require increased protection of equipment. Especially at risk are free-standing areas of power plants far away from the main building, e.g. control units of a fuel storage, of water processing or telecontrol installations. Furthermore, solar and wind power plants also require special attention regarding surge protection.

• Nuclear power plants

Quality and realiability are of great importance for power plants, but even more so for nuclear power plants. This applies especially to all components of the containment-area. All installations in the safety area are subjects to strict testing. The goal is the lowest possible change in characteristics of electrical equipments, such as insulation resistance and voltage drop.

The basis for the certification of products through local authorities are mostly the ANSI / IEEE - standards 323-2003 and 344-1987(R1993).

Weidmüller products have successfully passed numerous tests.

The elements of equipment qualification (EQ) testing are:

• Radiation ageing: the equipment is subjected to the full predicted accumulated radiation it will be exposed to over the station’s lifespan.
• Thermal ageing: the test simulates a working lifetime at high ambient temperature by means of a shorter period at a much higher temperature.
• Seismic resistance: a vibration test that simulates a predicted earthquake event.
• Loss of coolant accident (LOCA): the LOCA test simulates the environmental conditions within the containment area following a primary reactor coolant leak.

Weidmüller provides EQ-tested products. We have supplied suitable terminals and terminal box assemblies to scores of power plant projects around the world. In many places, our products have had to pass additional, stringent, special testing to meet local standards.
