Single Core Aluminum 6.35/11kV Medium Voltage Power Cable

.6.35/11kV medium voltage power cable has an armored jacket that protects the cable from external attack. Armoring should be used in all mechanically corrosive installations. The inner jacket has metal wires or strips as armor. The outer jacket protects the wires from mechanical and chemical damage, and its uniform deep red coating is impermeable to water, weather, impact and abrasion.

 

characteristics

 

 

Aluminum MV power cables are widely used in various applications due to their ability to reliably transmit medium voltage power. For example, utility distribution networks, renewable energy projects, for connecting generators, transformers, and grid interfaces; in large industrial facilities; infrastructure, and buildings, such as tunnels, airports, railways, and highways etc.

Certification

 

 

Our medium voltage power cable is SAA certified, with certification numbers SAA242046 and SAA250307. With increasing awareness of certification among contractors, distributors, and end users, SAA certification helps differentiate us from the competition. Certification acts as a market "passport," making marketing and promotional efforts more persuasive. Furthermore, certification not only signifies the compliance of our wires but also represents the quality experience of Greater Wire Manufacturer (Geritel Wire is a brand).

Production Line

 

thhn cable factory

 

Greater Wire manufacturer provides customized product services. According to the customer's own project needs, it can put forward requirements for conductor materials, insulation materials, sheath materials, colors, etc. The factory meets these needs through flexible production arrangements. For example, some industrial applications require special cables that are resistant to high temperatures, or construction projects require halogen-free and low-smoke cables. The factory can produce corresponding cable products according to specific requirements. Customized services enable factories to better meet the personalized needs of customers and enhance market competitiveness. In order to ensure the continuity of the production process, Greater Wire usually maintains a certain amount of raw material inventory, such as copper, aluminum, insulation materials, and sheath materials. At the same time, inventory management of finished cables is also crucial. The factory needs to reasonably arrange the finished product inventory according to order requirements and market forecasts to avoid excess or shortage of inventory.

FAQ

 

Q: How to deal with medium voltage power cable overload?

A: When medium voltage power cable is overloaded, the current load should be reduced immediately. Long-term overload may cause cable overheating and insulation damage, and the cable cross-section needs to be increased or heat dissipation needs to be improved.

Q: What is the local repair of MV cable?

A:  Local repair of MV cable is to repair local insulation damage by using heat shrink tubing or cold shrink tubing to restore the insulation performance of the cable.

Q: How to choose medium voltage cables suitable for underground laying?

A: Medium voltage cables suitable for underground laying should have strong mechanical strength, moisture resistance and corrosion resistance. Armored cables or cables with moisture-proof layers are common choices.
