XHKXS, XUHKXS and XRUHKXS Cables

Key Features: XHKXS Cable

• Application: Medium voltage Copper / MDPE power cable for power distribution networks.
• Suitability: For direct burial and installation in ducts in external power distribution networks. 
• Standard & Voltage Rating: IEC 60502-2, Generally to HD620 10-R. 6/10kV, 8.7/15kV, 12/20kV and 18/30kV. 
• Construction: Class 2 Stranded Copper conductor, Cross-Linked Polyethylene (XLPE) insulation, Copper wire screen, and Medium Density Polyethylene (MDPE) outer sheath.
• Details: Optional waterblocking: single (longitudinal) and dual (Longitudinal & radial). Single core cables (3-core also available).  

The MDPE-sheathed XHKXS, XUHKXS and XRUHKXS cables are designed for power distribution projects in Poland. Using the Polish cable nomenclature, they are manufactured to IEC 60502-2 (extruded insulation with a voltage rating from 3kV to 30kV) and generally meet the requirements of HD 620-10R.

XHKXS Cable Specification & Applications

Available in voltages of 6/10kV, 8.7/15kV, 12/20kV and 18/30kV, these cables are for power networks in Poland. 

The Copper conductors with their associated current carrying capacity produce cables in smaller overall diameters than the Aluminium XHAKXS equivalent. This makes them particularly suited where space constraints limit the installation. 

The robust MDPE outer sheathing provides environmental protections, offering tear and abrasion resistance as well as UV resistance, ideal for external installation in ducts or directly buried. The lack of flame retardant properties would deter internal installations, particularly should CPR compliance be required.

XUHKXS and XRUHKXS Cable waterblocking properties

Some installation environments will benefit from the cable having additional protection against water ingress, provided as a longitudinal swellable tape either side of the metallic screen, and with optional additional waterblocking tape on the underside of the sheathing.

The Al/PET tape that provides the radial waterblocking acts when tightly bonded to the sheath acts to prevent ingress should the sheathing be compromised, whilst the longitudinal waterblocking prevents water being pulled throughout the length of the cable as a result of the capillary action from the pressure contained within the cable construction.

The equivalent cables are more commonly referenced using the German nomenclature under N2XS(F)2Y and N2XS(FL)2Y (for XUHKXS and XRUHKXS respectively).
