Huanyu Cable manufactures medium voltage XLPE power cables from 3.6/6 kV up to 26/35 kV for substations, industrial facilities, utility distribution and infrastructure projects. Copper and aluminium conductor, unarmoured, STA and SWA constructions are reviewed against IEC 60502-2, applicable GB/T requirements or the confirmed project specification.
Representative medium voltage cable image for structure and specification review. Final construction is confirmed against the project specification before quotation.
Huanyu Cable supplies medium voltage XLPE power cables for distribution networks, substations, industrial plants, renewable energy grid-connection projects and large facilities. Cable construction is reviewed according to the confirmed voltage class, route conditions, conductor material, screen design, armour requirement and documentation scope.
Typical Chinese model references for MV cable construction families include YJV, YJY, YJV22, YJV23, YJV32 and YJV33. Steel tape armour and steel wire armour are selected by installation conditions, while conductor, sheath and final project designation are confirmed project by project.
Representative constructions are listed for initial selection. Final cable type, voltage class and testing scope are confirmed during specification review.
XLPE insulated, PVC or PE sheathed medium voltage power cable for protected fixed installations where additional mechanical protection is not required.
Steel tape armoured medium voltage power cable for applicable multicore constructions requiring radial mechanical protection, with PVC or PE sheath options.
Steel wire armoured medium voltage power cable for applicable multicore constructions requiring higher mechanical or tensile protection, subject to route and circuit design.
Conductor material, screen design, sheath material, flame-retardant or LSZH requirements can be reviewed against confirmed specifications.

Huanyu Cable reviews MV cable requirements from 3.6/6 kV up to 35 kV classes, including common 6/10 kV, 8.7/15 kV, 12/20 kV, 18/30 kV, 21/35 kV and 26/35 kV projects.
YJV or YJY are unarmoured XLPE insulated MV cables. YJV22 and YJV23 use steel tape armour. YJV32 and YJV33 use steel wire armour.
Copper and aluminum conductor options can be reviewed per project, based on voltage class, conductor size, route design and confirmed specifications.
IEC-based medium voltage cable requirements can be reviewed project by project against the confirmed cable design, testing scope and documentation requirements.
The selection depends on installation route, mechanical protection, pulling conditions and project specification. Unarmoured, STA and SWA designs should be confirmed before quotation.
Flame-retardant or LSZH sheath requirements can be reviewed where the project specifies fire-safety or smoke-performance requirements for the MV cable route.
