General information

Short Summary
A major nuclear engineering company in the Czech Republic seeks a European company able to provide a supply of special heat-resistant and radiation-resistant wire with a special isolation system.
The technology need consists of:
- Coil winding wire
- Coil connection wire
- Coil winding covering coat/sealing
Full Description
In the past, the company used a kind of wire developed during the last century for the rocket launcher industry. This long-used wire is unavailable on the market at this moment.

The requirements for the wire are very specific. The coils wound from the required wire (including the covering coat/sealing) will be exposed to hydrogen and helium atmosphere of temperature about 325 °C, for around 40 years. The expected total absorbed radiation dose over the 40-year time is 4*10^6 Gy.

Electrical characteristics:
- Material: copper or copper alloy
- Resistance approx.: R = 0,019 Ω*mm^2/m
- Breakdown voltage: VBR < 100 V

Winding wire:
- nominal core diameter approx.: d = 0,3 mm
- diameter of wire including the isolation: d < 0,5 mm

Connecting (jumper) wire:
- nominal core diameter approx.: d = 0,5 mm
- diameter of wire including the isolation: d < 0,8 mm

Similar types or dimensions are subject to discussion. Wires’ isolation must be compatible with the covering coat/sealing. The covering coat/sealing should not degrade in any way over time, withstanding the environment stated above. The coat/sealing shall be applied:
- on the coil frame,
- on each of the wiring layers during coil winding
- for overall reinforcement and covering of the coil
The mean diameter of the coil core: d = 9 mm.

In the current situation, The company would like to select a potentially suitable sample and get the testing batch in over the next 4 months. Then, type certification/qualification of the supply should take place over the next 6 months. Subsequently, the product will be deployed in operation.
