RITZ Instrument Transformers - Cast-Resin Bus Bar Systems

RITZ provides a range of cast-resin bus bar systems, which provide an alternative to parallel-connected cables.

Cast-resin solid-insulated bus bar systems

RITZ cast-resin SIS solid-insulated bus bar systems are available up to 72.5kV and 7,000A. They are especially useful for transmission of higher currents and/or limited space requirements, providing a cost-effective and save alternative to parallel-connected cable systems, metal-enclosed bus bar or bus duct systems.

Cast-resin bus bars benefits

Specific benefits of our cast-resin bus bars include:

• Compact design
• Reduced requirements for the installation space
• Small bending radii
• 3-dimensional geometric shape is possible
• Natural cooling due to effectual conductor design
• High opererational reliability due to factory routine test of each bus bar
• No maintenance

Safety benefits include:

• Touch safe
• Fully insulated and capacitive graded system
• High thermal and dynamic short-circuit current withstand capabilities
• Excluded phase to phase short circuits
• No toxic fumes in case of fire: self-extinguishing
• High operational reliability due to routine test for each bus bar element

Cast-resin bus bar construction and installation

We provide a range of construction and installation for cast-resin bus bars. Installation is simple due to its standardised nature.

Cast-resin bus bar service

We minimise the project engineering customers have to do, by providing a complete engineering service for bus bar routing, including a fixation system as a 3D CAD model, complete installation documentation, and supervisor support.

Electronic instrument transformers and sensors

We provide voltage-sensoric electronic instrument transformers and sensors. They feature voltage up to 90kV, accuracy of 0.2%, and frequency from 0kHz to 10kHz.

RITZ also offers current-sensoric electronic instrument transformers and sensors. They feature current up to 24,000A, accuracy of 0.01%, and frequency from 0kHz to 10kHz.

Applications include:

• Power engineering
• Grid analysis
• Traction power distribution systems
• Protection technology
• Elektro-chemistry
• Switchgear systems
• Environment engineering
• Automobile industry research

Customised cast-resin parts for electrical equipment

We provide development and formulation of cast-resin moulding materials for electrical applications in low and medium-voltage ranges and for electronics, as well as design and production services for cast-resin mouldings such as special bushings and fuse housings.

Under the trading name RITZ Instrument Transformers, RITZ has been pooling its activities to gather new strengths since 1 August 2007. The tradition and knowledge of the parent company RITZ Messwandler Hamburg and the subsidiary RITZ Messwandler Dresden (TuR) have been united with the companies Wandler- und Transformatoren-Werk Wirges (WTW) and Messwandlerbau Bamberg (MWB) under this name. This merger unites a total of more than 200 years of know-how in instrument transformers production.

The overseas corporations of RITZ Instrument Transformer in Austria (Marchtrenk), Hungary (Kecskemét) and China (Shanghai) strengthen the company's position on the international market.
