FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What governing standard and construction define CCT (CCT 6.35/11 kV Covered Conductor Thick (XLPE) Overhead Distribution Line Cable)?

CCT (CCT 6.35/11 kV Covered Conductor Thick (XLPE) Overhead Distribution Line Cable) is manufactured in accordance with AS/NZS 3675 / EN 50397-1 for 6.35/11 kV – 19/33 kV service over -25 °C to +90 °C. Its 2-layer construction comprises stranded aluminum conductor, xlpe covering core insulation.

What is the minimum bending radius and installation temperature for CCT?

The minimum installed bending radius for CCT is 15 × OD across its continuous operating temperature range of -25 °C to +90 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of CCT arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded aluminum conductor (High-conductivity aluminum conductor per AS/NZS 3675 / EN 50397-1); (02) XLPE covering core insulation (Extruded XLPE covering dielectric (continuous layer)).

What factory test certificates are supplied with CCT?

Every production drum or spool of CCT undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per AS/NZS 3675 / EN 50397-1, and is delivered with an EN 10204 3.1 factory test certificate.
