8.7/15KV 12/20KV High Voltage CPE Sheathed EPDM Insulation Rubber Flexible Tinned Copper Core Cables for Shield Tunneling Machines in Open-pit Mines
8.7/15KV Heavy Duty Flexible Rubber Sheathed Flexible Cables for Shield Machines In Open-pit Mines. UGEFP cables are high voltage rubber sheathed flexible cables designed for shield machines in open-pit mines. Featuring high abrasion resistance, oil resistance, cold resistance, high-temperature resistance, waterproofing, and corrosion resistance, they are suitable for harsh construction environments. Suitable for heavy equipment in open-pit mines and underground tunneling operations rated at 8.7/15kV or below, such as shield tunneling machines. Also applicable for tunnel projects in subways, railways, highways, hydropower facilities and so on.
Key Features

Applications
UGEFP cable is a rubber-insulated flexible cable designed for shield tunneling machines. It is suitable for power connections in distribution networks of systems such as shield tunneling machines and mining equipment, with rated voltages not exceeding 8.7/15kV and 12/20KV.
- Shield Machine Operations: Provides stable power supply to the cutterhead and propulsion system of shield machines, while also transmitting control signals.
- Mining Operations: Power supply for heavy equipment like excavators and loaders, plus underground power transmission in mines.
- Subway Construction: Power supply for tunnel boring machines, plus electricity for lighting, ventilation, and other equipment in subway stations and tunnels.
- Distribution Networks for Similar Equipment Systems: Power distribution and signal transmission for equipment like port machinery and cranes.
Product Advantage
This cable utilizes tinned copper conductors. The tin coating acts as a protective layer, isolating the copper from contact with air, moisture, and corrosive media. This effectively prevents oxidation and corrosion of the copper, maintaining low resistance at conductor connection points. It ensures stable current transmission, avoids increased energy consumption or equipment failures caused by excessive contact resistance, and delivers more stable electrical performance.
