Product Standard

TJ/CL313-2014、EN50264-2-1:2008、BS 6853、DIN 5510

Scope of Application

This products are suitable for the distribution system and power-supply system of railway vehicles and rolling stock that the rated voltage is 3.6/6kV or less than 3.6/6kV.

Including: 0.6/1 kV unshielded unsheathed wire,1.8/3kV unshielded unsheathed wire, 1.8/3kV unshielded sheathed wire,3.6/6kVun shielded sheathed wire.

The products are suitable for non-high concentration acid-alkali pollution and oil pollution occasion which have low-smoke halogen-free flame-retardant requirements.

Application Characteristics

Silicone rubber insulated automotive low-voltage wires

1. Rated voltage level: 300V (to ground).

2. Temperature resistance characteristics: Long-term working temperature 105°C, short-circuit overload temperature 160°C (5 seconds).

3. Lower operating environment temperature: -40°C.

4. Bend radius in fixed scenarios: 10 times the outer diameter of the cable; in mobile scenarios: 5 times the outer diameter of the cable.

5. Mechanical physical properties: The cable is made of high-strength special polymer materials. The peel performance, wear resistance, oil resistance, low-temperature resistance and cut-through resistance of the insulation layer all meet the requirements of EN50306-2: 2002 standard.

6. Flame retardant properties: Passed the single vertical test in EN50265-2-1 and the bundled combustion test in EN50305. In a DC system, the higher voltage between the cable conductor and the ground does not exceed 1.5 times the rated voltage U₀.

Note: "U₀" represents the voltage applied between the insulated conductor and the ground, "U" represents the voltage applied between the conductors of a two-core or multi-core cable or the system voltage of a single-core cable, and "Um" represents the higher voltage of the equipment system.

2. Temperature resistance characteristics: Long-term working temperature 90°C, cumulative 20,000 hours of temperature resistance 120°C, short-circuit overload temperature 200°C (5 seconds).

3. Lower operating environment temperature: -40°C. 

4. Bend radius: In fixed applications, it is 5-8 times the outer diameter of the cable; in mobile applications, it is 4 times the outer diameter of the cable.

5. Insulation or sheath: It uses the EI104 and EM104 types of cross-linked elastomer materials as specified in the EN50264-2-1 standard.

6. Flame retardancy: It passes the single vertical burning test in EN50265-2-1 and the bundled burning test in EN50266-2-4 (for cable outer diameter D > 12mm), EN50266-2-5 (for cable outer diameter 6mm < D < 12mm), and EN50305 (for cable outer diameter D < 6mm) as per the EN50265-2-1 standard.

7. Oil resistance: The finished cable has excellent oil resistance, and the oil resistance of its sheath complies with the provisions of the EN50264-2-1 standard.

8. Acid and alkali resistance: The finished cable sheath passes the acid and alkali resistance tests as per the EN50264-2-1 standard.

9. Safety: The insulation layer and sheath of the finished product have halogen-free properties, low smoke properties, and a safe level of halogen content in accordance with the EN45545-1 standard.
