APPLICATIONS
TECHNORAY-3 halogen free single-core wires are intended for fixed and mobile connections in vehicles, rolling stock and transport. Wires can also be used for control, protection and monitoring systems or power supply.
The wires are designed to offer high flexibility combined with tensile strength.
Continuous operation at higher temperatures and a high level of fire safety is offered due to application of electron beam crosslinked halogen free compound insulation.
Halogen free wires are applied in locations where, in case of fire, higher safety level for human beings and expensive electronic equipment is required. The wires are flame retardant and their smoke emission is low, emitted fumes are non toxic and non corrosive.
The wires are designed for frequent contact with petroleum products. The wire insulation is then made of special halogen free compound meeting oil resistance requirements of Polish standard PN-EN 60811-404.
Wires are approved by the Institute of Railways for use in vehicles, rolling stock and transport.
CONSTRUCTION
- flexible, multiwire conductors, stranded of annealed tinned copper wires, meeting requirements of class 5per PN-EN 60228,
- dual wall insulation made of electron beam crosslinked halogen free compound (EI 104), black, other colours also available.
