Mining Cable Construction

Flexible Conductors

Mining rubber cables commonly use stranded copper conductors to provide the flexibility required by their intended application. Conductor cross-section, stranding arrangement, electrical resistance and conductor class depend on the selected cable specification.

Where applicable, conductor requirements may be specified with reference to IEC 60228 or the corresponding conductor requirements of the relevant Chinese cable standard.

Rubber Insulation

Rubber-based insulation materials may be selected according to the rated voltage, conductor operating temperature, electrical properties and environmental requirements of the cable. The insulation compound and thickness must correspond to the applicable product design and standard.

Screening and Monitoring Arrangements

Selected mining cable models incorporate semiconductive screens, metallic screens or monitoring conductors. These elements serve different functions depending on the cable construction and the associated electrical protection system.

Screening and monitoring arrangements must be specified according to the relevant cable model, voltage rating, equipment design and applicable safety requirements.

Grounding Conductors

Where a grounding conductor is incorporated, its construction and cross-section must comply with the applicable electrical system and cable requirements. Grounding connections must be correctly installed and maintained according to the equipment manufacturer’s instructions and relevant electrical safety regulations.

Rubber Outer Sheath

The outer sheath provides mechanical and environmental protection for the internal cable components. Depending on the selected compound, the sheath may be designed to meet specified requirements relating to abrasion, mechanical strength, moisture exposure and flame propagation.

The suitability of the sheath for oil exposure, sunlight, outdoor installation, continuous movement or other special operating conditions must be confirmed for the particular cable model.

Operating Temperature and Bending Radius

Operating temperature and minimum bending radius are important considerations when selecting flexible mining cables. These parameters depend on the cable construction, insulation system, sheath material and intended operating conditions.

The original product information identifies maximum continuous conductor temperatures of 65°C and 90°C for different cable categories. It also specifies minimum bending radii of six or fifteen times the overall cable diameter for selected models.

These values must not be applied universally to all mining cable types. The correct temperature limit and bending radius should be confirmed from the technical datasheet and applicable standard for the exact cable model.

For installations involving frequent bending, cable reeling, dragging or continuous mechanical movement, additional requirements may apply. A cable suitable for general flexible connections is not necessarily suitable for continuous reeling or repeated dynamic flexing.

Applicable Standards and Technical Requirements

Mining cables may be subject to different national, industry and international requirements depending on their voltage rating, construction, intended application and destination market.

GB/T 12972 – Flexible Rubber-Sheathed Cables for Mining Purposes

The GB/T 12972 series covers various categories of flexible rubber-sheathed cables for mining purposes. Different parts address specific cable types, rated voltages and construction requirements.

Examples include flexible mining cables for mobile equipment, coal-cutting machinery, screened cable constructions, mining drill cables and light-duty mining applications. The applicable part and edition must be identified for the selected cable model.

MT/T 818 and KA/T 818 – Mining Cable Industry Standards

The MT/T 818 series has been used for various categories of cables intended for coal mining applications, including mobile flexible cables and specialized mining cable constructions. Certain related standards are now identified under KA/T designations.

For projects requiring a particular Chinese mining industry standard, the applicable standard number, part, edition and current designation should be confirmed before production.

IEC 60228 – Conductors of Insulated Cables

IEC 60228 provides conductor requirements that may be relevant when specifying conductor construction and electrical resistance. Its applicability must be evaluated together with the complete cable specification.

International Market and Mining Safety Requirements

International mining projects may require additional electrical, mechanical, fire-performance or approval requirements. Depending on the application and destination market, purchasers may request evaluation against relevant IEC or EN standards, or specific national mining safety requirements.

For example, mining cables intended for certain applications in the United States may be subject to applicable MSHA requirements. Such requirements must be reviewed for the intended cable application and cannot be assumed from a Chinese mining cable designation alone.

References to GB/T, MT/T, KA/T, IEC, EN or MSHA are provided to help identify possible technical and regulatory requirements. They do not constitute a claim that every cable supplied by Insight Cables complies with these standards or holds any specific approval.

How to Select the Right Mining Cable

Rated Voltage and Electrical System

Select a cable with a rated voltage appropriate for the electrical system and equipment. The voltage class must correspond to the intended operating conditions and applicable cable standard.

Conductor Size and Core Configuration

Conductor cross-section should be determined according to load current, cable length, installation conditions and permissible voltage drop. Grounding, control and monitoring conductor requirements must also be considered.

Screening and Protection Requirements

Screened cable constructions may be required for particular voltage classes, mining machinery or protection systems. The screen design and monitoring arrangements must be compatible with the equipment and relevant safety requirements.

Mechanical Movement and Bending

Consider whether the cable will remain relatively stationary, move occasionally, be dragged during equipment operation or undergo repeated bending. These operating conditions affect the required flexibility, construction and minimum bending radius.

Environmental and Flame-Retardant Requirements

Moisture, abrasion, oil exposure, sunlight and other environmental factors should be evaluated. Where flame-retardant performance is required, the applicable test method, acceptance criteria and supporting documentation must be specified.

Installation and Safety Considerations

Mining electrical cables must be selected, installed, inspected and maintained by qualified personnel in accordance with the applicable electrical regulations, mining safety requirements and equipment manufacturers’ instructions.

Where grounding conductors are provided, they must be correctly connected to the designated protective grounding system. Damaged cables, compromised insulation and defective terminations must be addressed before equipment is returned to service.

The original product information also advises against prolonged sunlight exposure. Actual outdoor and UV resistance must be verified for the selected sheath compound rather than assumed for all mining rubber cables.
