6.35/12Kv Medium Voltage Power Cables 3 Core Anti-Termite Wire

Medium voltage power cables have a relatively low coefficient of thermal expansion, and the cable dimensions do not change much. This feature ensures that the cable will not affect the installation quality under the conditions of thermal expansion and contraction, maintain good electrical connections, and reduce the risk of failure caused by temperature changes.

Min. installation temperature: 0°C

Operating temperature: -25°C to +90°C

Emergency operating temperature: 105°C

Max. Short Circuit Temperature: 250°C

Application

6.35/12 kV medium voltage power cable with 3 core anti-termite protection is suitable for areas where underground utilities are threatened by termite infestation, as well as for power distribution and rural electrification projects. At this voltage level, it is widely used in regional power grids, agricultural processing plants, and power feeders across areas with high soil activity. Its three-core aluminum or copper conductor configuration supports balanced medium-voltage power transmission and is suitable for small substations, irrigation pumping stations, and industrial parks requiring long distances

Feature

• Conductor: Stranded Compacted Circular aluminum conductor as per AS/NZS 1125

• Conductor Screen: Extruded Semi-conductive compound

• Insulation: XLPE

• Insulation Screen: Extruded Semi-conductive compound

• Longitudinal Water blocking : Water blocking tape above and below copper screen (Optional)

• Metallic Insulation Screen: Copper Wire Screen + helically applied copper tape

• binder tape/sheath over assembled cores

Composite sheath

• Inner layer: Extruded Polyvinyl Chloride, Colour: Orange

• Termite Protection: Polyamide (Nylon -12)

• Outer layer: HDPE (Black)

Certification

Medium voltage cables have obtained SAA certification, with certification numbers: SAA242046 and SAA250307 (available on the certification website). In construction projects, cable quality is directly related to the safety and stability of project operations. SAA certification for cables is equivalent to passing a multi-level quality inspection system. It verifies that the cables meet standard requirements for conductor cross-section, insulation uniformity, sheath abrasion resistance, and mechanical impact resistance, ensuring they provide long-term stable power supply and withstand external environmental influences. For power companies, contractors, and design institutes, choosing SAA-certified cables means selecting high-quality, proven cables that meet specifications, reducing potential operational risks.

FAQ

Q: Can Anti-Termite wire be used in marine environments?

A: Anti-termite wire, which is typically treated with chemical additives to prevent termite damage, is primarily designed for terrestrial environments where termite infestation is a concern, such as underground installations or areas with significant wood structures. In marine environments, however, the primary concerns are saltwater corrosion, UV exposure, and potential biofouling (accumulation of marine organisms like algae and barnacles).

Anti-termite wires are specially coated or made from corrosion-resistant metals (e.g., stainless steel or copper-nickel alloys). For a marine environment, it's essential to use cables rated specifically for saltwater exposure, often with protective jackets, which resist both UV and saltwater.

Q: Are medium voltage power cables suitable for powering electric motors?

A: Yes, medium voltage power cables are suitable for powering motors, especially in industrial and large applications where high power is required. But attention needs to be paid to voltage matching, and current carrying capacity, and the cable must be rated for the full load current of the motor. Cable insulation and protection.

Q: Do cables need to be marked?

A: Yes, cables usually need to be properly marked to ensure compliance with regulatory requirements, improve safety and facilitate maintenance management.
