YnOGY / YnOGYek / YnOGYekm PVC Mining Cable 0.6/1 kV

YnOGY mining cable is a flexible 0.6/1 kV power cable for stationary and portable mine equipment. Its Class 5 copper conductors have PVC insulation, with an inner PVC sheath and a yellow flame-retardant outer sheath. The YnOGY, YnOGYek and YnOGYekm constructions provide different screening arrangements within the same power, protective and control-circuit selection family.

Select the circuit layout before choosing the conductor size. Unscreened YnOGY is available with four conductors for three-phase power and protection, or with five or seven conductors when one or three control circuits are required. YnOGYek has three individually semiconductive-screened power cores, one bare protective conductor and one insulated control core. YnOGYekm uses individual copper-wire and plastic-thread braid screens, with five- and seven-conductor arrangements.

Choose the screen to match the mine installation. YnOGY serves areas without an explosion hazard. The screened constructions address the specified methane and coal-dust application categories; the equipment protection arrangement and local mine classification remain part of cable selection. Their individual power-core screens have different materials and should be identified explicitly in the enquiry.

The tables retain each model’s complete conductor configuration, maximum diameter and cable weight. They also separate model-specific electrical data. Provide the full model and configuration, route length, installation duty, mine classification and termination details for quotation. Allow a minimum bend radius of 6 times the cable diameter in fixed installation and 10 times the diameter for movable equipment connections.

Explore the mining and tunneling cable range for related configurations.

For armoured underground roadway distribution and screened face-machine feeders, compare these mining cable constructions: Fixed Mining Power Cable — PVC / HEPR, SWA / STA Options (for PVC or 90 °C HEPR-insulated stationary mining power cables with SWA or STA metallic armour); Mine Feeder Type 1 Screened Machine Cable 1.1/1.1 kV (for 1.1/1.1 kV individually screened flexible rubber feeder cables supplying underground coal-face machines). Verify whether the route is a fixed gallery hanger run or a semi-mobile machine supply before ordering.

Construction

The representative image shows unscreened YnOGY 3 × 6 + 6 mm²: three power cores and one black corrugated protective core arranged compactly around a central filler, with PVC inner and yellow outer sheaths. The screened ek and ekm variants use the separate constructions below.

Applications

Use the model-specific screen and conductor layout to supply stationary or portable electrical equipment in underground, open-pit and strip mining installations.

• YnOGY: equipment power supply in mine areas without an explosion hazard.
• YnOGYek and YnOGYekm: screened equipment connections for the specified methane classes a, b and c and coal-dust classes A and B; state the site classification and acceptance requirements with the enquiry.
• Four-conductor YnOGY layouts for three power circuits and one protective circuit.
• Five- and seven-conductor layouts where the equipment needs an additional one or three control circuits.
• Supported fixed routes and movable equipment connections within the stated bend and installation-temperature limits.
• Coordinate glands, strain relief and the protective-conductor connection with the complete cable configuration.

For underground mine roadway installation practices and gassy-mine power-plus-monitoring cables, review these resources: Armoured and Static Mining Cable: Fixed Distribution Routes (detailing mechanical armour selection, suspension intervals, and fault-loop earthing on fixed underground routes); 1-CBEH 0.6/1kV Gassy Mine Cable with Control and Monitoring Cores (for 0.6/1 kV 1-CBEH gassy-mine cables combining main power conductors with integrated control and earth-monitoring cores). Confirm methane-zone earth-leakage protection, armour earthing continuity, and outer sheath flame retardancy.

Specifications

A configuration such as YnOGYek 3 × 10 + 10 + 6 mm² means three 10 mm² power conductors, one 10 mm² protective conductor and one 6 mm² control conductor.

Electrical values belong to the named screen construction. The current table uses AC or DC operation below 25°C; apply route, grouping and thermal corrections for the actual installation.

Maximum diameters and calculated weights are configuration-specific. Check cable entries and handling arrangements against the complete ordering designation.

Select the cable with the mine’s equipment-protection and acceptance requirements; identify the methane and coal-dust class in the enquiry.
