Flexible Electric Trailing Rubber Cables for use in mines

Application

The rubber sheathed flexible cables are mostly used as power cable for equipment in industry work such as boilers, heating plates, hand lamps, transportable motor etc. They can be installed at medium mechanical stress in dry, damp and wet areas as well as in open air and in agriculture plants. These cables are also suitable for fixed installation on plaster, in temporary buildings and residential barracks. They are suitable for direct laying on components and mechanical parts of machines like lifts and cranes.

The cables are able to be used in case of protected and fixed installation in tubes or in equipment as well as rotor connecting cable of motors with a working voltage up to and including AC 1000V or DC 750V against ground.

They are designed to provide high flexibility and have the capacity to withstand weather, oils, mechanical and thermal stresses. The cable is resistant to ozone and weather effects.
