The full name of YTTW is flexible fireproof metal sheath inorganic mineral insulated cable.

1. YTTW mineral insulated cable is developed on the basis of BTTZ mineral insulated cable, aiming to maximize strengths and avoid weaknesses, and manufacture a new generation of mineral insulated cables.

2. The difference from BTTZ fireproof cable is that it is made of multi-strand copper wires twisted and non-combustible inorganic insulating material, and its fireproof performance is better than that of BTTZ fireproof cable.

It is suitable for power transmission in places where the rated voltage 0.6/1KV is easily affected by fire or directly affected by fire, and where the rated voltage 450/750V is easily affected by fire or directly affected by fire, etc. Controlling, monitoring circuits and protection circuits are multi-purpose in important buildings and facilities that are relatively closed or crowded, such as high-rise buildings, subways, stations, airports, power stations, hospitals and shopping malls.

1. Product model: YTTW

2. Product name: low-smoke halogen-free sheathed cable with copper core mica and mineral insulation corrugated copper sheath

3. Rated voltage: 0.6/1kV

4. Executive standard: GB/T 34926-2017

5. Use characteristics:

a) Excellent fire resistance. At a flame temperature of 950°C, a voltage of 750 volts is applied between the combustion phases and the outer sheath, and the insulation will not be damaged for 90 minutes. Class B burns at a flame temperature of 750 to 800°C. A voltage of 750 volts is applied between the phase and the outer sheath. The insulation is not damaged after 90 minutes.

b) It is flexible and can be coiled on the cable drum, and the bending radius is greater than 20D

c) No smoke when burning, non-toxic insulation adopts inorganic materials, no harmful gas will be produced when the non-combustible body burns, and secondary pollution will not occur

d) The cable not only has a large carrying capacity, but also has strong overload capacity, good corrosion resistance, strong safety performance, no electromagnetic interference, and long service life
