Type 210 Flexible Rubber Mining Cable for Boring Machines
Type 210 flexible rubber mining cable is a compact 1.1kV cable for hand-held boring machines and drills. The design combines three flexible screened power cores, a central pilot core and a heavy-duty PCP outer sheath. This makes the cable easier to route around portable equipment while retaining a defined screen and control path for the machine connection.
Quick Suitability Check
| Suitable for | Hand-held boring machines, mining drills and comparable portable equipment circuits. |
|---|---|
| Confirm before use | Actual current, cable length, voltage-drop limit, bending route, connector system and site standard. |
| Not established by the supplied sheet | Continuous flex life, minimum bending radius, tensile load, travel speed, temperature limits and water/oil performance ratings. |
Engineering Features
- Flexible tinned copper: Fine stranded tinned annealed copper supports repeated hand positioning and helps keep the conductor surface suitable for damp mining conditions.
- EPR insulation: Ethylene propylene rubber provides the primary insulation system shown in the source data.
- Screened core design: Semiconductive insulation screens and the composite copper screen give the cable a defined electrical interface for equipment termination.
- Pilot core: A flexible stranded tinned copper pilot is available for the machine’s control, interlock or monitoring circuit; confirm the termination scheme with the equipment maker.
- PCP outer sheath: The heavy-duty sheath protects the laid-up cores during normal workshop and mine-site handling. Final mechanical and environmental limits must be confirmed for the installation.

The table reproduces the supplied Type 210.1 rows. Confirm the required conductor size against machine current, route length and permitted voltage drop; do not substitute a larger size without checking termination space and handling characteristics.
Applications
Use this cable family where a portable mining tool needs a flexible 1.1kV supply and a screened multi-core construction. The supplied application is hand-held boring machines and drills; fixed feeder, reeling, festoon or submerged duty requires a separate mechanical and environmental review.
Standards and Documentation
| AS/NZS 1802:2003 | Listed in the supplied Type 210 reference. |
|---|---|
| AS/NZS 1125 | Listed in the supplied Type 210 reference. |
| AS/NZS 3808 | Listed in the supplied Type 210 reference. |
| AS/NZS 5000.1 | Listed in the supplied Type 210 reference. |
Certificate scope, edition year, routine tests and project inspection documents should be confirmed at quotation stage rather than assumed from the model name.
Selection Notes for Buyers
- State whether the cable is hand-held, trailing, reeling or fixed; the supplied application only establishes hand-held boring machines and drills.
- Provide current, voltage, route length and allowable voltage drop so the conductor size can be checked.
- Confirm the pilot-core function, screen bonding and termination space with the machine builder.
- Share minimum bend, pulling, abrasion, oil, water and temperature requirements; these values are not supplied in the reference sheet.
- For replacement orders, send the existing marking and a cross-section photo because similar 1.1kV mining cables can have different screens or pilots.
Request a Type 210 Cable Quotation
Send the required Type 210.1 size (1.5 or 2.5mm² as shown, or a requested custom size), length, quantity, machine model, termination, site environment and documentation requirements. TEBAOFLEX can then confirm construction, packaging and inspection details before production.
