OVERHEAD CONDUCTOR

LUMINO’S LOW LOSS CONDUCTOR SOLUTION
FOR RENEWABLE SECTOR

Nowadays world is moving towards Green/Renewable energy. Line Loss is crucial factor in renewable energy transmission. Aside climate change and global warming pose serious threats to our planet and to the quality of life of next generations. It is imperative to limit the emission in the atmosphere of greenhouse gases (e.g. CO2, CH4, N2O) by reducing I2 R Losses of transmission lines. Our Low Loss Type conductor (hereinafter called “3L conductor”) can reduce transmission losses by 41% compared to equivalent ACSR Conductor. Renewable lines adopting our 3L conductor can operate more effciently, reducing the need of electricity from power stations. These latter can then reduce their per unit cost, as well as CO2 emission

3L – LOW LINE LOSS CONDUCTOR

Lumino’s 3L conductor is specially designed for renewable sector for distribution and transmission lines. It is designed to operate continuously at temperatures up to 85°C without loss of strength, it designed with High conductivity Al and Special Alloy.

ADVANTAGE

CONSTRUCTION

3L, a homogenous conductor, is a concentric-lay stranded conductor made from TW shape wire high conductivity aluminium 1370-H19 wires and core having round wire of Special Al Alloy.

APPLICATIONS

3L conductors are useful for:

SPECIFICATIONS

Luminos 3L conductor meets or exceeds the following International specifications:

ASTM B230 Specification for Aluminium Wire for Electrical Purposes.
AS/NZS-1531 Specification for Alloy Wire for Electrical Purposes.
