Features

01

Limited current

The working current is limited to a certain extent. For example, when the ia level is working normally and there are one or two faults, the current is limited to less than 100mA; when the ib level is working normally and there is one fault, the current is limited to less than 150mA, so as to avoid sparks and explosions.

02

Low capacitance and low inductance

Both the capacitance and impedance are smaller than ordinary cables, and it has the characteristics of distributed low capacitance and low distributed inductance.

03

Good shielding performance and anti-interference performance

It can effectively prevent electromagnetic interference and line crosstalk, and is suitable for use as a transmission line in circuits such as distributed systems and automated detection and control systems in occasions with protection requirements. Special sheath color: The sheath is generally blue, which is easy to distinguish from ordinary cables and is conducive to maintenance and wiring.

Step 4

Use

001
Oil and gas industry
Explosion-proof intrinsically safe communication cables are widely used in oil drilling platforms, oil field production facilities, natural gas extraction, transmission pipelines and other places, where flammable and explosive gases often exist.
002
Chemical plant
In the production and storage process involving chemicals (such as flammable and explosive gases and liquids), explosion-proof intrinsically safe communication cables provide a safe electrical connection solution.
003
Coal mines
In environments with dust explosion hazards such as coal mines, the use of explosion-proof intrinsically safe communication cables can ensure the safe operation of communication lines.
004
Power industry
In the control systems and monitoring systems of energy fields such as thermal power, nuclear power, wind power, and photovoltaics, explosion-proof intrinsically safe communication cables are also often needed.
005
Power system and electrical equipment
In the field of aerospace, the high temperature resistance, cold resistance, and corrosion resistance of silicone rubber cables make them an ideal choice. It is widely used in cable connections for aircraft electrical systems, wires, sensors, radar equipment, etc., and can withstand environmental changes under extreme conditions such as high-speed flight and drastic temperature differences.
006
Military and Aerospace
Communication cables that need to be used in extreme environments, such as equipment control and data transmission in explosive environments.
