Description:
NH represents fire resistance, which is the addition of a layer of mica tape between PVC insulation and copper conductors to separate the flame from the conductor during external fire. It can provide normal power supply for a certain period of time, but its insulation material is the same as ordinary BV wires; And ZR represents flame retardancy, which is the addition of flame retardant fuel to PVC insulation to prevent external insulation from delaying combustion and automatically extinguish after the fire source is eliminated. The principle is different, but the NH level is still higher. Fire-resistant copper core PVC insulated twisted flexible cable fire alarm cable,Fire engineering, broadcasting, lamp head line.
1. Applications
NH-RVS wire is called copper-cored PVC insulated stranded connection use soft wire , pair twisted multi-stranded soft wire, referred to as twisted pair cable, commonly known as "flower wire","fire wire" in China. At present, this kind of wire is mostly used in Fire engineering system, broadcasting, lamp head line
2. Standards
NH-RVS cable implements the standards GB/19666, And it can also be made to comply with CE, SGS, SAA PSE standards, etc. In addition, we can design and manufacture the products as the requirements of customers.
3. Structure
1. Suitable to be installed in electrical power transmission and distribution lines rated voltage 300V or lower.
2. conductor's rated working temperature:≤70
3.Short-circuit temperature160/5sec
4. Cable laying environment≥0
5. Cable laying, bend radius≥10 times cable O.D.
4. Feature
1. NH-Rvs cable is mostly used for the detector circuit of the fire alarm automatic alarm system.
2. Suitable for household appliances, small power tools, instrumentation, and power lighting. A double white core is used for direct connection to the lamp line; a red and blue core is used for fire protection, alarm, etc.; a red and white core is used for broadcasting and telephone lines; a red and black core is used for broadcasting lines.
3. NH-Rvs cable is used to connect the amplifier and audio equipment, and the broadcast system transmits the audio signal amplified by the power amplifier.
