Product information

Category: INDUSTRIAL CABLES

Product overview

RG7H1R is a single-core screened power cable with Class 2 compact copper, G7 HEPR insulation and a red PVC outer sheath. The supplied energy-cable catalogue covers U₀/U 1.8/3 to 26/45 kV, with voltage-specific rows for conductor size, diameter, weight, current, resistance, reactance and capacitance. The 26/45 kV entry should be selected as a higher-voltage project grade rather than assumed interchangeable with a standard 6/10 or 12/20 kV construction.

Use the single-core format where the power route and termination design call for individual phase cables. The catalogue pairs this model with a separate three-core RG7H1OR cable; the two have different metallic screens and physical dimensions. Match the cable’s copper-wire screen and bonding plan to the switchgear or transformer interface, then calculate current rating using the actual trefoil or flat arrangement and burial conditions. Source current values are reference data, not a universal installed rating.

A 3.6/6 kV, 1 × 10 mm² airport-lighting configuration appears in another supplied document. Its bare-copper tape shield, nominal dimensions and ENV 50213 reference belong to that airport series-circuit configuration only. Confirm the required airfield circuit drawing before ordering. Explore the industrial cable range for related power cables.

Construction

RG7H1R is HEPR-insulated and PVC-sheathed. The insulation material should not be mistaken for a rubber outer jacket. The general energy-cable construction is:

RG7H1R standard single-core construction
Layer	Energy-cable construction
Conductor	Class 2 compact plain-copper strand
Conductor screen	Extruded semiconductive layer at U₀/U ≥6/10 kV
Insulation	G7 HEPR rubber, lead-free in source catalogue
Insulation screen	Extruded, cold-strippable semiconductive layer at U₀/U ≥6/10 kV
Metallic screen	Plain-copper wires with helically wound tape
Outer sheath	Red Rz-quality PVC compound

Airport-lighting configuration

The separate 3.6/6 kV airport-lighting variant specifies compact bare copper, extruded inner and outer semiconductive layers, G7 rubber insulation, a bare-copper tape shield and red PVC sheath. This is a source-listed variant requiring its own approved order drawing; its dimensions and shield do not apply to the general RG7H1R energy-cable grades.

Applications

RG7H1R energy cable is used for power transmission between transformer rooms and large loads, in air, ducts, channels or project-approved underground routes. Select cable spacing, copper-screen bonding and termination according to the installation method and fault duty. For the general energy cable, reference installation guidance gives a 0 °C minimum laying temperature, recommended 12 × OD bending radius and 60 N/mm² recommended maximum pulling stress based on copper section.

For airport primary lighting, the separate 3.6/6 kV RG7H1R configuration serves the series circuit between constant-current regulators and isolation transformers, or between isolation transformers. Its fixed-service temperature and bend guidance differ from the general energy-cable document. Compare RG7H1OR three-core cable when three phase cores must share one outer sheath.

RG7H1R 1 × 10 mm² 3.6/6 kV airport lighting	2.3	0.075	1.4	14	305

Airport configuration: fixed 0 to +90 °C; minimum bending radius 15 × OD. General energy configuration: max conductor +90 °C; minimum operating −15 °C without mechanical shock; minimum laying 0 °C; recommended bend 12 × OD. Use the airport dimensions and tape shield only for the airport configuration.

Standards

The general energy-cable design references CEI 20-13 and IEC 60502 as construction and electrical reference standards, EN 60332-1-2 for flame propagation, and CEI 20-16 / IEC 60885-3 for partial-discharge measurement. The airport-lighting variant separately references ENV 50213. The source range includes a 26/45 kV grade; verify the standard edition and scope applicable to that grade in the project specification.

Request the project-specific drawing and required test documents with the exact voltage and airport or energy construction.
