Waterproof 8.7/15KV 12/20KV EPDM Insulation Tinned Copper Conductor
Mobile Rubber Flexible Power Cable Wire for Shield Tunneling
Machine in Open-pit Mines
UGEFP cables are high voltage rubber sheathed flexible cables
designed for shield machines in open-pit mines,which feature wear
resistance, oil resistance, cold resistance, water resistance, corrosion resistance and so on. They are suitable for harsh
construction environments. They are mainly applied to 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.

Product Quick Details
- Rated power frequency voltage U0/U: 8.7/15KV,12/20KV
- Conductor: Stranded Tinned fine copper wire conductor with
excellent electrical conductivity and flexibility
- Insulation: The power conductor insulation utilizes EPDM rubber,
offering excellent electrical insulation properties, heat
resistance, and aging resistance; the ground conductor core is made
of semiconductive rubber to ensure grounding safety.
- Insulation Shield: Rubber-type semiconductive outer shielding
effectively evens out the electric field and prevents partial
discharge.
- Outer Sheath: CPE(Chlorinated polyethylene),features high abrasion
resistance, oil resistance, cold resistance, high-temperature
resistance, water resistance, and corrosion resistance
- Operating temperature range: -35°C to 65°C
- Maximum operating temperature of conductor: +75°C
- Minimum bending radius exceeds 6 times cable diameter
- Tinned copper conductor prevents oxidation and improves
conductivity
- Features: Flexible, waterproof, tensile resistant, explosion-proof,
oil-resistant, corrosion-resistant, high abrasion resistance

Application Scenarios
- 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
- High Abrasion Resistance: The outer sheath withstands prolonged
friction from minerals and other materials without damage.
- Torsion Resistance: Strong resistance to twisting prevents
deformation and sheath cracking.
- Water resistance, corrosion resistance: Maintains stable
performance in environments containing water or corrosive liquids.
