The power, control cable and related circuits involved in this unit can reduce the harm to people and improve the safety of transportation in case of fire. For the cables with or without sheaths, the insulation and sheath shall be halogen-free materials. In case of fire, the product of this unit can limit the spread of flame, reduce the emission of toxic gas and smoke, reduce the loss of visibility and make personnel evacuate quickly.
This product is applicable to the fixed wiring of vehicles and the transmission of electric energy of junction box with little softness. It is suitable for power devices of vehicles with miniaturized electric wire and cable.
1、 The rated AC voltage of the cable is 300V.
2、The operation temperature of the cable is－40℃～105℃. The maximum short-circuit temperature shall be 160℃, 5s. In case of fire, such cables have excellent performance in preventing flame spreading, smoke and toxic gas emission.
3、Safety: The chlorine content of the cable is 0, so there is no hydrogen chloride gas overflowing during overheating or combustion, and there is no damage to people, instruments and meters.
4、The outer diameter of the cable is small and the weight is light. The cable adopts a single-layer insulation structure, and its outer diameter is smaller than that of the two-layer structure.
5、 Allowable bending radius of cable: For fixed laying, it is 4 times of cable outer diameter; for non fixed laying, it is 6 times of cable outer diameter.
6、The cable meets the low-smoke and halogen-free performance. The gas release testing during cable combustion meets the requirements of total halogen gas < 5mg/g, pH value ≥ 4.3, conductivity≤10us/mm and light transmittance≥70%.
7、Toxicity index: The equivalent European standard toxicity index shall not be greater than 3, and the equivalent TB standard toxicity index shall not be greater than 5.
8、 The cable can be used in the occasion polluted by mineral oil and fuel oil.
9、The cable is resistant to single cable vertical burning.
10、Solvent resistance, acid and alkali resistance.
