High-voltage submersible mining cable
The higher-voltage submersible version uses waterproofed EPR and CM rubber sheath layers around screened power and earth cores. Its document covers 8.7/15 and 12/20 kV configurations for pump, dredger and floating-dock feeds.
Where it is used
Submersible medium-voltage supply to pumps, dredgers and floating equipment in saline or brackish water, after project-specific depth and termination review.

Installation limits
Submersion suitability depends on cable ends, joints, pressure, water chemistry and installation. Do not use the 300 m figure as a guarantee for an unreviewed assembly.
Technical datasheets
Standards named in the datasheets are design or test references; request the applicable certificate and test evidence for the exact product configuration.
Request a configuration review
Send the voltage, conductor size, core arrangement, moving or fixed duty, bend radius, environment, required length and quantity to TEBAOFLEX. We will confirm the construction and commercial details for the project.
