D.C cable specially for Light Rail Transport application

The cables are used in dense locations as subway tunnel device and stations. Once fire happening, the close environment would make fleeing and fire protection difficult. So it concludes that the laid cables in dense locations must have high flame resistance as well as not bringing smoke and deleterious gas with halogen. Therefore, it would decrease“the second disaster” for machines and apparatus and the cables have performances of sunlight resistance.waterproof and resistance to gopher Generally.the cables are suitable for subway tunnel device.between electric cable net and subway for power transformation 0f D.C.

D.C cable specially for Light Rail Transport Service Condition

1. DC cable conductive core of long-term allowable working temperature should not exceed 90 ℃.
2. short-circuit the longest duration of no more than 5s. Its conductive core of the maximum temperature does not exceed 250 ℃.
3. the ambient temperature while laying should not be less than O ℃.
4. the minimum bend radiusshould be not less than 12 times the cable diameter.

5. LSZH features: Meet GB / T 17560-1998 and GB / T 17651-1998 requirements;

D.C cable specially for Light Rail Transport Features

1.conductivity ≤ 10μs/mm; 2.DH value ≥ 4.3.
3.cable burning smoke density transmittance ≥ 60%.
4.smoke toxicity achieve public safety cable combustion safety level two levels:
5. the cable flame retardant meet GB/T18380.3-2001 cable burning test requirements for Class A;
6. the cable waterproof performance is excellent. Long-term immersion in water use, and has little effect on its electrical properties.
7. the cable has UV protection properties. UV resistance can fully meet the requirements of GB 14049 standard: Cable in the atmosphere and sunlight effects of aging, the sample after 42 days aging, the tensile strength and elongation at break sheath change rate should not exceed ± 30%; after 21 days of aging, the sheath tensile strength and elongation at break change rate should not exceed ± 15% range.
8. the cable has a rodent performance. By comparison with the blank sample. After two consecutive weeks tests. Specimen protection rate ≥ 95%.
9. can produce other models according to user needs and specifications of the DC cables. May also improve the cable temperature rating to 125 ℃.
