Fire Resistant Control Cable NH-KVV
Rated voltage: U0/U is 450/750V.
The long-term working temperature of the conductor core is 70°C and 95°C, and the cable laying temperature is not lower than 0°C.
Flame retardant control cable: It is mainly suitable for use in industrial and mining enterprises, energy and transportation departments, for control of AC rated voltage below 450/750 volts, proximity and protection lines, etc. PVC insulated and PVC sheathed control cables used in occasions.
Power cables are cables used to transmit and distribute electrical energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. Power cable is a cable product used to transmit and distribute high-power electrical energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulation power cables.

Magnesium oxide insulated fireproof cable--BTTZ
The copper core copper sheathed magnesium oxide insulated cable is called MI cable abroad, and is referred to as mineral insulated cable or fireproof cable in China. It is a modern building wiring cable and special industry (metallurgy, chemical industry) made by special technology using high-conductivity wire as conductor, inorganic magnesium oxide as insulation, and seamless copper tube as sheath (see cable structure diagram). , oil, etc.) with cables. Due to the particularity of its material and structure, it is determined that the product has electrical properties, mechanical properties, environmental resistance and environmental protection properties that are unmatched by organic cables (plastic cables).
Mainly include glued copper conductor, inorganic mineral insulating layer, metal sleeve isolation layer, color separation isolation layer, halogen-free filling strip, mineral fireproof layer, high flame retardant tape, low-smoke halogen-free sheath from the inside to the outside. made. Although the melting point of aluminum is only 660°C, the expanded refractory layer extruded on the outside of the aluminum tube is foamed and solidified under the attack of the flame, forming a thick barrier to block the direct injection of the flame to the aluminum tube. The integrity of the aluminum tube is preserved, and the heating temperature of the outer mica tape is reduced to below 600°C.
Flexible Metal Sheathed Fireproof Cable--YTTW
The conductor of YTTW series metal sheathed inorganic mineral insulated power cable adopts multi-strand copper stranded wire, the insulation is mechanically wrapped with high temperature resistant synthetic mica tape, the insulating layer is densely filled with alkali-free glass fiber, and the sheath is longitudinally wrapped with copper tape and then welded It is formed into a copper tube, and then corrugated by continuous rolling. For specific requirements that the metal sheath cannot be exposed, a layer of polyolefin (low smoke and halogen free) sheath can be added on the outside.
Flexible Mineral Insulated Fire Resistant Cable--BBTRZ
Large current-carrying capacity: Under the same conditions, the current-carrying capacity of BBTRZ cable is larger, and the rated current-carrying capacity of its conductor operating temperature of 90°C is basically equivalent to the current-carrying value of BBTZ cable operating temperature of 125°C, which is much higher than other cables.
