Description
Technical Field
The utility model belongs to the technical field of control cable, concretely relates to low smoke and zero halogen flame retarded control cable.
Background
The control cable is often used in industrial and mining enterprises, energy transportation departments and the like, and the existing control cable has many disadvantages when in use, for example, the cable is easy to produce harmful gas in the heating process, and if a fire disaster occurs, the cable is flammable, the spread of the fire can be aggravated, and a large amount of smoke and harmful gas can be emitted at the same time, so that the life safety is seriously threatened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art and providing a fire-retardant, thermal-insulated, low cigarette, no halogen's control cable.
The technical scheme of the utility model as follows: the utility model provides a fire-retardant control cable of low smoke and zero halogen, includes the cable core that a plurality of rules were arranged, the outer cladding of cable core has the insulating layer, the outer cladding of insulating layer has first shielding layer, it has the filler to fill between first shielding layer and the insulating layer, the outer cladding of first shielding layer has the insulating layer, the outer cladding of insulating layer has second shielding layer, the outer cladding of second shielding layer has the sheath, the insulating layer material is irradiation crosslinked polyethylene, the sheath material is low smoke and zero halogen polyolefin.
Preferably, the cable core is formed by winding an oxygen-free copper wire or a galvanized copper wire.
Preferably, the first shielding layer and the second shielding layer are both oxygen-free copper mesh braids, the coverage rate of the first shielding layer is not lower than 90%, and the coverage rate of the second shielding layer is not lower than 80%.
Preferably, the filler is a glass fiber rope.
Preferably, the thermal insulation layer is a ceramic fiber tape.
The utility model has the advantages that:
(1) the sheath material is low-smoke halogen-free polyolefin, so that the high-temperature-resistant performance is good, a large amount of smoke is not generated when the high-temperature-resistant material is heated, harmful gas is not emitted, and the environment is protected;
(2) the insulating layer material adopts irradiation cross-linked polyethylene, has good flame retardance and high temperature resistance, and does not contain harmful substances;
(3) glass fiber rope fillers and ceramic fiber tape fire insulation layers are added in the cable, so that the fire resistance and heat insulation performance of the cable are further improved.
