Typical applications of CABLES FOR POWER TRANSMISSION

Select...
Underground distribution Substation interconnections

Underground distribution cables

These insulated cables are buried to distribute medium-voltage power within urban and suburban areas.

Substation interconnections

Heavy-duty cables used within substations to connect transformers, switchgear, and circuit breakers. They must handle immense electrical stresses and fault currents to enable voltage transformation and power routing.

FAQs (Frequently Asked Questions) about cables for power transmission & distribution

Yes. Our XLPE-insulated, lead-sheathed or corrugated aluminium-sheathed cables are designed for direct burial and duct installation, replacing overhead lines in urban and sensitive environments.

Both copper and aluminium conductors are available. Aluminium is commonly used for cost and weight savings on large-section cables, while copper is preferred for compact, high-current urban circuits.

Our cables are subject to a rigorous quality programme including conductor resistance, partial discharge, high-voltage withstand, with factory visits in Barcelona always available for customers.

Yes. We have supplied cables to major underground transmission schemes, substation projects, and grid reinforcement programmes internationally. Our project engineering team can review specifications, provide technical submittals, and support the approval process with network operators, system integrators, and main contractors.

Underground MV distribution uses XLPE single-cores. Top Cable’s X-VOLT RHZ1 (Al or Cu, 6/10-18/30 kV) is the standard buriable choice.

Substation interconnections use MV/HV cable. Top Cable’s X-VOLT RHZ1/HEPRZ1 covers 10-69 kV transmission.

Aluminium is lighter and cheaper per amp; copper is more compact and conductive. Top Cable’s X-VOLT offers both conductor types for distribution.

Top Cable’s X-VOLT RHZ1 18/30 kV is an XLPE-insulated MV cable with a copper screen, halogen-free sheath and 90C rating, made to IEC 60502-2.

Top Cable’s X-VOLT RHZ1/HEPRZ1 single-cores link transformers and switchgear in distribution substations.

Cross-section is set by load current, voltage, short-circuit rating and laying method. Size it against the ampacity tables in Top Cable’s X-VOLT datasheets.

Top Cable’s X-VOLT (AS) MV cables carry a CPR reaction-to-fire class (Cca, EN 50575) for regulated distribution installations.

For around 66 kV, Top Cable’s X-VOLT range extends to 69 kV with aluminium or copper conductors and XLPE/HEPR insulation.

Top Cable’s X-VOLT RHZ1: XLPE insulation, Al or Cu class-2 conductor, copper-wire screen (min. 16 mm2), halogen-free sheath, 6/10-18/30 kV, to IEC 60502-2 / HD 620.

Top Cable manufactures the X-VOLT MV range (RHZ1, HEPRZ1, 6/10-69 kV) for power transmission and distribution networks.
