2GTL Cable for Transformers, Generators and Motors
2GTL cable is a halogen free single core cable designed for transformers, generators and motors working under high or low temperature conditions. Its silicone rubber insulation, rubber compound inner sheath and outer glass fibre braid help provide heat resistance, flexibility and improved mechanical performance for demanding electrical equipment connections.
Key Features
- Wide voltage range: Available in 1.1/1.9kV, 3.3/4.2kV, 6.6/7.2kV and 13.9/15kV ratings for different motor, generator and transformer connection requirements.
- High and low temperature performance: Rated from -50°C to +180°C for equipment operating in demanding temperature conditions.
- Halogen free construction: Designed for applications where reduced corrosive gas emission and safer material selection are important.
- Flexible tinned copper conductor: Class 5 flexible tinned copper supports easier installation and reliable conductivity.
- Glass fibre braid protection: The outer fibre glass braid enhances the mechanical properties of the cable.
- Resistance to industrial media: The cable offers good resistance to molecular density oils, vegetables and animal fats, alcohols and seawater.
