A: product features and uses

This product is suitable for the rated AC voltage of 450/750V or below mobile or fixed laying electrical instrument connection line or signal transmission, cable has good thermal stability, can maintain good electrical performance and softness in high temperature, low temperature, corrosion, suitable for metallurgy, electric power, petrochemical and other industries with mobile temperature resistance and other special requirements for use.

Two: product implementation standards

Q/HHTZH004.2

Flame retardant and fire resistance performance test GB12666-90 standard

Three: Use features

1. Rated AC voltage: U0/U 450/750KV

z.u high operating temperature: 180℃

2. z.u Low ambient temperature: silicone rubber sheath: fixed dressing -60℃, non-fixed dressing -20℃

3. The cable installation and laying temperature should not be lower than -20 ° C.

4. The allowable bending radius of the cable is 6 times of the outer diameter of the non-armored cable

Four: basic model and name

Note: 1 If flame-retardant silicone rubber cable is required, add ZR before model;

The silicone rubber insulated nitrile sheathed cable replaces the silicone rubber insulated and sheathed heat resistant control cable in the case of a large number of cores and a large section. The application situation is similar to that of the silicone rubber sheathed cable, and the long-term use temperature is -60-105℃.

The copper wire in the conductor core can be tinned.

Five: code name and meaning

Table 2
