Medium Voltage Power Cable

Medium voltage cables(MV) are manufactured using the Monosil process. We offer the highly specialized factories, leading research facilities and exacting quality control procedures necessary for the manufacture of PVC insulated cables up to 6KV and XLPE/EPR insulated cables for use at voltages up to 35 KV. Throughout the production process, all materials are kept under clean controlled conditions to ensure absolute homogeneity of the finished insulation material.

Suitable for energy networks such as power stations,distribution system etc. It usually used for installation in ducts, underground and outdoors.

Due to its robustness and high electrical stability, medium voltage cables are used in harsh environments.

3.8/6.6kV is a more common voltage rating compared to BS standards (Particularly BS6622 and BS7835 specifications), where applications can benefit from the mechanical protection provided by their aluminium wire or steel wire armoured (depending on single core or three core configurations). The cables would be well suitable for fixed installations and providing power to heavy-duty static equipment because its rigid construction limits the bending radius.

Electric cable with copper conductors, semi conductive conductor screen, XLPE/PE insulation, semi conductive insulation screen, copper tape metallic screen of each core, PVC bedding, galvanized steel wires armoured (SWA) and PVC outer sheath. Suitable for energy networks where mechanical stresses is expected. Suitable for underground installation or ducts installation.

Suitable for energy networks such as power stations, distribution system etc. Suitable for installation in pipes, underground and outdoors.

Aluminum wire armor (AWA) for single-core cables and steel wire armor (SWA) for multi-core cables provide strong mechanical protection, making these 11kV cables suitable for direct burial underground. These armored medium voltage power cables usually have copper conductors, but aluminum conductors are also available according to the requirements of the same standards. Copper conductors are stranded (Class 2), while aluminum conductors meet standards for use of stranded wire and solid (Class 1) construction.

15kV is the voltage usually specified for equipment cables (including ruggedized mining equipment cables manufactured to IEC 60502-2), but is also relevant for British Standard armored cables. While mining cables may have a strong rubber sheath to provide abrasion resistance, particularly for towing applications, the BS6622 and BS7835 standard cables are sheathed in PVC or LSZH material and mechanically protected by a layer of steel wire armoured.

Suitable for energy networks such as power stations,distribution system etc. Used for installation in ducts, underground and outdoors.

The cables manufactured to BS6622 and BS7835 are generally supplied with Copper conductors with Class 2 rigid stranding. Single core cables have aluminium wire armoured (AWA) to prevent induced current in the armoured, whilst the multi-core cables have steel wire armoured (SWA) providing the mechanical protection. These are round wires with over 90% coverage.

Note: Red outer sheath can be prone to fading when exposed to UV rays.

The single core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 3.8/6.6KV to 19/33KV and the frequency is 50Hz. They are mainly suitable for installation in power supply stations, indoors and in ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.

The 33KV triple core power cables are small part of our range of medium voltage(MV) cable, it is suitable for installation on power networks, grid,underground, outdoors in cable ducting.

Copper or Aluminium Conductors, single core or three core, armoured or unarmoured, bedded and served in PVC or non-halogenated material, rated voltage 6.6 up to 33kV, manufactured according to SANS or other National or International Standards.

Copper or Aluminium Conductors, single or three core, armoured or unarmoured, bedded and served in PVC or non-halogenated material, rated voltage from 6,6kV up to 33kV, manufactured according to SANS or other National or International Standards.

The 11kV medium voltage(MV) electric power cable use copper conductors, semiconductor conductor shield, XLPE/cross-linked polyethylene insulation, semi-conductive insulation screen, copper tape metallic screen, PVC bedding, Aluminium wire armoured (AWA) and PVC outer sheath. The cable is suitable for rated voltage from 6,6kV up to 33kV in accordance with SANS or other National or International Standards.

15kV CU 133% TRXLPE Fully Neutral LLDPE is mainly used for primary underground power distribution in pipeline/conduit systems, suitable for use in wet or dry place, direct burial, underground pipeline, and locations exposed to sunlight. When used at voltage of 15,000v or lower, the conductor temperatures not to exceed 90°C during normal working.

25kV cable is suitable for use in wet and dry areas, conduits, ducts, trenches, trays, direct burial and where electrical performance is superior when installed closely with a grounded conductor complying with NEC Sections 311.36 and 250.4(A)(5) Properties are required. The cables are capable of continuous operation at conductor temperatures not exceeding 105°C in normal operation, 140°C in emergency overload conditions, and 250°C in short-circuit conditions. Cold bend rated to -35°C. ST1 (Low Smoke) is rated for sizes 1/0 and larger. The PVC sheath is made with SIM technology and has a coefficient of friction COF of 0.2. The cable can be installed in the conduit without lubrication. Rated for maximum sidewall pressure of 1000 lb/ft.

35kV CU 133% TRXLPE Fully Neutral LLDPE is mainly used for primary underground power distribution in conduit systems, suitable for wet or dry locations, direct burial, underground duct and places exposed to sunlight. Normal operation uses voltages of 35,000v or less, conductor temperatures not exceeding 90°C during normal operation.

Power distribution or secondary transmission network cable are commonly used as main supply for Commercial, Industrial and urban residential networks. Suitable for high fault level systems rated up to 10kA/sec. Can provide structures with higher fault current ratings upon request.

For efficiency and longevity, each MV medium voltage cable is tailored to the installation, but sometimes a truly custom cable is required.

In each case, technical data is provided to demonstrate suitability and specifications carefully engineered for manufacture. All custom solutions are subject to intensive testing at our MV cable testing facility.
