1： Product features and uses: This product is suitable for mobile or fixed electrical instrument connection lines or signal transmission with AC rated voltage of 450/750V and below. The cable has good thermal stability and can maintain good electrical performance and flexibility in high temperature, low temperature, and corrosive environments. It is suitable for use in industries such as metallurgy, power, and petrochemicals with special requirements for mobile temperature resistance.

2： Product execution standard Q/HHTZH004.2 Flame retardant and fire resistance characteristics test execution GB12666-90 standard

3： Usage characteristics

1. Rated AC voltage: U0/U 450/750KV Maximum operating temperature: 180 ℃ 2 Minimum ambient temperature: Silicone rubber sheath: fixed installation -60 ℃, non fixed installation -20 ℃

3. The temperature for cable installation and laying should not be lower than -20 ℃.

4. Allowable bending radius for cables: The minimum allowable bending radius for non armored cables is 6 times the outer diameter of the cable

4： Basic model and name

Note:

1. If you need flame-retardant silicone rubber cables, add ZR before the model number;

2. Silicone rubber insulated nitrile sheathed cables can replace silicone rubber insulated and sheathed heat-resistant control cables when there are many cores and large cross-sections. The applicable situation is similar to that of silicone rubber sheathed cables, and the long-term use temperature is -60-105 ℃.

3. Copper wires in conductor cores can be plated with tin.

5： Code name and meaning
