The difference between MYP cable and MY is that the former is shielded and the latter is not. Both can be used for mobile coal mining equipment, but MYP has a stronger anti-interference.
The latest production standard of MY-0.66/1.14 cable is MY818.5-2011.
Power core insulation shielding using semi-conductive extruded cladding or semi-conductive tape cladding. The cross-sectional area of single-core cable is from 4mm2 to 400mm2. Three-core ground-connected cable cross-section area from 4 mm2 to 300 mm2.
Rated voltage (U{{0}}/U)O 0.66/1.14. The minimum bending radius of the cable is 6 times the diameter of the cable.
The operating ambient temperature of the cable is -45-+60 degree , and the ambient temperature of laying is not lower than -10 degree . The long-term working temperature of the cable conductor should not exceed 70 degree . Aluminium sheathed cable has good shielding performance and the comprehensive sheath has certain shielding performance, which can be used in the trunk line of the electrified section of the railway or in the area of strong electric interference. The bending radius of the cable is not less than 15-20 times of the outer diameter.
MY cable is the abbreviation of mobile rubber sheathed flexible cable for coal mine.M stands for coal mine,Y stands for mobile flexible cable.MY cable is used for power connection of mobile coal mining equipment under the mine. The voltage level is {{0}}.38/0.66KV.
1. Strong abrasion resistance: dust, rocks, etc. in the mining environment will cause wear and tear on the cable, the rubber cable is made of abrasion-resistant rubber material, which can effectively resist wear and tear.
2. good oil resistance: the mine is often accompanied by oil, rubber cables with special surface treatment, so that it has good oil resistance.
3. Cold and humidity resistance: low temperature in the mine, high humidity, rubber cable can work normally in the temperature range of -40 degree to 60 degree .
4. high tensile strength: there are often a large number of mechanical equipment in the mine, the rubber cable is reinforced with a steel wire braid layer, has a high tensile strength.
1. Conductor: made of high-purity electrolytic copper or aluminium wire to provide a conductive path for power transmission or control signals.
2. Insulation: made of special rubber material with good electrical insulation properties.
3. External Rubber Jacket: made of high quality rubber material, resisting abrasion and oil, ensuring the mechanical protection and stable electrical performance of the cable.
4. steel wire braid layer: increase the mechanical strength and tensile properties of the cable, improve the tensile capacity.
