Instrumental signal cable in intrinsically safe explosion-proof circuit
Product Description
Implemented standard
Q/HY01-2005 standard is equivalent to BS5308 standard
Flame-proof property accord with GB/T18380.3 (idt.IEC60332-3).
Characteristics and Application
The product is a kind of instrumental signal cable with low capacitance, low inductance and excellent ex-Plosion characteristics. It has excellent shield property and anti-interference property. It is used in chemical industry, petrochemical, electrical power, gas engineering, mine industry in which explosion danger exists and explosion-proof safety is required. The cable is for transmitting automatic control signal.
