TRATOS MTO®-MH-FU

Used as the suspended cable for intrinsically safe control of user-operated mine hoists (lifts) with the telephonic connection in underground mines. TRATOS MTO rubber-sheathed flexible cables can be operated as self-supported cables of length up to 200 m with a safety factor of 5.

Finely stranded copper conductor, tinned, Class5 (refer to DIN VDE 0295). The cable is concentrically laid-up around a central steel support element in order to make the cable strongest possible.

Outer sheath material TRATOS MTO, basic material PCP, compound type: 5GM5, colour blue (refer to DIN VDE 0207, part21).

The electrical parameters are as follows: rated voltage: 0,6/1kv. Maximum permissible operating voltage in AC systems is 0,7/1,2kv. The maximum permissible operating voltage in DC systems is 0,9/1,8kv. The AC test voltage is 4kv. The current carrying capacity is according to DIN VDE 0298, part 4. The ambient temperature for fully flexible operation is -30℃ to +80℃ and for fixed installation is -40℃ to +80℃. There is also a low-temperature version “K” available with the following temperature range: -60℃ to +60℃ for fully flexible operation and also for fixed installation.

The maximum tensile load is 15N/mm2. Suspension length max. 200m with a safety factor of 5. The minimum bending radii according to DIN VDE 0298, part3. The travel speed max. 1,5m/s. The cable is resistant to oil according to DIN VDE 0473, part 811-2-1, paragraph 10.

The behaviour in case of fire is given to DIN VDE 0482, part 265-2-1, paragraph 10. The weather resistance is unrestricted use outdoors and indoors, resistant to ozone and moisture.
