Oil-resistant medium-voltage trailing cable
The SMK construction is a red rubber trailing cable with screened EPR-insulated cores, synthetic-yarn torsion protection and dimensional options at 3.6/6 and 6/10 kV. It is described for heavy mechanical duty in mining and transfer equipment.
Where it is used
Moving mine equipment, lift and transfer trolley systems where the installation conditions match the selected SMK configuration.

Installation limits
Oil and flame performance should be confirmed against the project test requirement; do not assume every installation or operating speed is covered by the same build.
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.
