FAQ

Questions engineers ask first

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

What governing standard and construction define ESUY (ESUY High-Flexibility Transparent-PVC Earthing & Short-Circuiting Copper Cable)?

ESUY (ESUY High-Flexibility Transparent-PVC Earthing & Short-Circuiting Copper Cable) is manufactured in accordance with EN 61138 / DIN VDE 0283-3 for Up to 36 kV Fault Duty service over -35 °C to +70 °C. Its 3-layer construction comprises stranded copper conductor, bare copper braid, transparent pvc tm2 sheath.

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

The minimum installed bending radius for ESUY is 5 × OD across its continuous operating temperature range of -35 °C to +70 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

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

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per EN 61138 / DIN VDE 0283-3); (02) Bare copper braid (Bare copper braid high-coverage braided layer (woven structure)); (03) Transparent PVC TM2 sheath (Extruded Transparent PVC TM2 sheath protective layer (continuous layer)).

What factory test certificates are supplied with ESUY?

Every production drum or spool of ESUY undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per EN 61138 / DIN VDE 0283-3, and is delivered with an EN 10204 3.1 factory test certificate.
