Power generation & distribution

Employing MULTILAM as core technology, Stäubli Electrical Connectors offers a wide range of connectors for use in low, medium and high voltage areas. We guarantee high performance and long-term reliability along the complete electrical supply infrastructure. Our established engineering capability for specialized customer applications makes us an outstanding partner and solution provider.

Example No. 1 – LA CUD

LA-CUD Multilam technology provides a technological advantage to switchgear. Allowing increased currents and lower power loss with limited insertion depths.

The LA-CUD Multilam, provides lower power loss at connection point providing better thermal management with decreased size in the bushing geometry compared to competitive solutions. The LA-CUD will not require pre-rolling and the groove removes the need for retaining rings and reduces the number of parts for customer to track in inventory.

Product used:

LA-CUD (Multilam Technology)

 

Example No. 2 - Power Transfromers

Barrier boards made of Transformer board provide drip-proof separation of the oil in the main tank from the oil in the tap changer compartment. Thus the risk a tap changer failure will have an impact on the transformer active part can be reduced. The tap changer is connected to the regulating winding and controls the voltage at the transformer terminals. The electrical connection between tap changer and regulating winding is made by the plug contact system on the barrier board for quick assembly.

Example No. 3 - High voltage test equipment

Systems for overall testing of current transformers, such as excitation test, insulation test, power frequency withstand test and accuracy test. For the latter an AC current source is used that supplies currents from < 1A up to 10‘000A using range switches which are capable of carrying currents of 2‘500A continuous and more than 5‘000A intermittent.

Example No. 4 - HV current transformer

Depending on the requirements, various forms of connection are used on the primary side of the instrument transformer; round bolts or flat connectors in various cross sections and hole patterns. A consistent adapter is required for all these connections in order to be able to connect and test the testing devices quickly, reliably, and at low resistance to the measurement converters.

 

Product used:

Fork plug GSRD 20 – 60

Example No. 5 - Busbar connection fork plug

Multi-Contact proposed a double fork HP-GSRD 100 to inter-connect the busbars of power supply containers with a tolerance up to +/- 10mm. The flat connector HP-GSRD is ideally adapted for the power distribution system for the mining industry, which are built to last in the toughest environments. This success strengthens Multi-Contact’s market position and broadens our experience in solutions for HV, MV and LV power distribution.

Example No. 6 - Busbar connection Rack Solutions

Rackable connector CLIPLAM CL-T for rapid replacement of power systems in wind turbines

Multi-Contact offered the rackable connector CLIPLAM CL-T. This withdrawal connection enables quick connections between two systems of double-pole insulated busbars. The contact is established through the MC MULTILAM, providing for low contact resistance and reducing the leakage inductance by up to 25% compared with bolted busbar connection. The Cliplam consist of:

 ▪ A plastic frame, that carries a fl at LA-CUT MULTILAM (No insulating function)

 ▪ Two plastic clips to fi x the frame on busbars (several thicknesses, from 2 to 5mm)

 

Product used:

Cliplam CT-08T-54

Example No. 8 - Panel receptacle on generator

Planned maintenance actions and foresight of power outage or covering of peak consumption are reasons for using of backup generators. Multi-Contact provides rapid connection systems for feeding into the low voltage grid.

The use of Multi-Contact standard products allows the client to achieve a high quality contact for mastered costs. The solution combines safe, easy and fast mounting:

▪ With bayonet locking, up to 5000 mating cycles

▪ Touch protected in unplugged condition (IEC, DIN EN 60529, VDE 0470-1)

▪ Clearly visible colour marking on the insulation

▪ IP65 in mated condition

 

Product used:

10BV, 16BV, 21BV
