It is used mainly for controlling, monitoring interlock circuits and protecting the circuits, responsible for transmitting controls and signals and widely applicable in petrochemical engineering, urban rail transit and data communications, etc. The control cable is able to safeguard the power supply and production system operation, whose role even outweighs that of the power cable trunk. In recent years in view of the rigid control of primary and secondary disasters after the fire in the field of industrial and civil equipment, we have developed different control cables that are fireproof, low-smoke, low-halogen and flame retardant.
The control cable mainly consists of several multicore Solid or flexible insulated wires(flexiblecontrol cable), with weaving copper wires surrounded or shield, screen and PVC sheath.
PVC insulated PVC sheathed control cable is used to connect electronic equipment. It applies to controlling, monitoring and protective system with A.C. rated voltage Uo/U up to and including 450/750 volts.
The main features of the flame retardant PVC controlled cable is difficult to catch on fire or that the continuous burning of cables is very limited when it is on fire. It applies to the places with special demands of flame retardant property.
Fireproof cable can operate normally for some time when it is burning except that it can transmit electrical power under normal condition. It is used in the places necessary to resist fire.
The feature of low-smoke halogen free flame retardant electric wire(cable) is also very low smoke emission and harmless(low toxic and low corrosive) besides the property of flame retardant, it is applied to the places with a special demands of flame retardancy, the density of smoke emission and toxic index if the cable is burnt, such as subway, tunnel, nuclear power station, etc.
