1-CBEH 0.6/1kV Gassy Mine Cable with Control and Monitoring Cores

1-CBEH Gassy Mine Cable with Control and Monitoring Cores

1-CBEH is a 0.6/1 kV flexible supply cable manufactured to DS 072-2004 for feeding motors on transferrable machines in gassy underground mines. What distinguishes it from a general monitored mining cable is the fixed core package: three working cores, a separate earth conductor, four control cores and a dedicated monitoring core, with a semiconducting filler and a semiconducting inner sheath.

That four-control-core arrangement is the reason this cable is specified by name. A machine wired for 1-CBEH expects four control cores plus the monitoring conductor at the terminal box; a cable with two or three control cores will not land on the same terminals even if its power cores match.

• Rated voltage: 0.6/1 kV; test voltage 3.5/2 kV.
• Core package: 3 working cores + earth + 4 control cores + monitoring core.
• Cross-sections: 3 × 25 mm² to 3 × 95 mm².
• Short-circuit temperature: +250 °C; conductor operating temperature +90 °C.

The cable is sufficiently resistant to shock and abrasion for underground machine duty, and can be produced with a textile braid under the sheath as the 1-CBEH spec variant. For German-standard monitored tunnel cable with KON/ST/ÜL marking see NSHCGEÖU KON+ST+ÜL.

1-CBEH Cable Construction

Nine-layer construction to DS 072-2004 with four identified core groups. The semiconducting strippable layer and semiconducting inner sheath are part of the monitoring path and must not be omitted when matching a build.

Designation elements

Conductor shape is RF. In the size table hl. is the monitoring conductor, so a build written 3 × 50 + 25 + 4 × 6 + hl. has three 50 mm² working cores, a 25 mm² earth conductor, four 6 mm² control cores and the monitoring conductor.

Optional construction

The cable can be produced with a textile braid under the sheath, designated 1-CBEH spec. State on the enquiry whether the braided variant is required, since it changes the outer diameter.

1-CBEH Applications

1-CBEH is used for flexible mains supply cords feeding engines on transferrable machines in gassy underground mines. The cable is sufficiently resistant to shock and abrasion for that duty.

• Motor supply to transferrable machines in gassy underground mines.
• Installations wired for a four-control-core plus monitoring-core terminal arrangement.
• Routes exposed to shock and abrasion within the stated bending radius.
• Machines requiring a separate earth conductor rather than a concentric earth.

Application boundaries

The control and monitoring core cross-sections follow the machine terminal box, so state the machine type with the enquiry, along with whether the textile-braided 1-CBEH spec variant is required and the drum lengths needed.
