What applications is CHKCYDY engineered for?

CHKCYDY 3.6/6 kV underground mining medium-voltage power cable built to PN-G-91006 with Class 2 copper phase conductors, HEPR insulation, overall concentric copper earth/screen, galvanized steel wire armour and red flame-retardant PVC jacket. It is built to PN-G-91006 / IEC 60502-2 for underground hard-rock & coal mining networks and mine shaft & inclined drift mv power feeders.

What are the minimum bending radius and operating temperature range for CHKCYDY?

The minimum bending radius for CHKCYDY is 12–15 × OD across its continuous operating temperature range of -30 °C to +90 °C, ensuring mechanical and dielectric stability in industrial service.

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

From inside to outside, the construction sequence is: (01) Phase Conductors (3x50 mm²) (Class 2 circular stranded plain annealed copper conductors for underground mining medium-voltage feeders); (02) HEPR Insulation & Rubber Filler (Natural-coloured high-modulus ethylene propylene rubber (HEPR) core insulation with extruded rubber interstitial filling); (03) Semiconductive Tape & Concentric Cu (Semiconductive binding tape wrapped with an overall concentric screen of bare copper wires and counter-helix copper tape); (04) Separation Sheath & Steel Armour (Extruded PVC inner separation sheath armoured with spirally applied round galvanized steel wires (SWA)); (05) Outer Sheath (3.6/6 kV Red) (Heavy-duty red ST2 flame-retardant polyvinyl chloride (PVC) outer sheath for 3.6/6 kV underground mine galleries).

What factory test certificates are supplied with CHKCYDY?

Every production drum of CHKCYDY undergoes routine electrical continuity, high-voltage dielectric and dimensional testing per PN-G-91006 / IEC 60502-2, and is delivered with an EN 10204 3.1 factory test certificate.
