Background technology
Along with the continuous progress of China's science and technology, and according to the needs of national conditions, the application of aluminium alloy power cable is had an optimistic view of energetically by insider, also very ripe by the technology continually developing innovation aluminium alloy power cable for many years, the peripheral product around aluminium alloy power cable exploitation also arises at the historic moment.But lack and can meet that crowds such as being applied to skyscraper, public place of entertainment, factory, hospital is relatively intensive, security grade high field institute, there is the low pressure pre-branched cable of the features such as flame-retardant.
Utility model content
The purpose of this utility model is that providing a kind of can be applied to the places that crowd is relatively intensive, security higher grade such as skyscraper, public place of entertainment, factory, hospital, has the flame-retardant aluminium alloy low pressure pre-branched cable of the features such as flame-retardant.
The purpose of this utility model realizes like this, flame-retardant aluminium alloy low pressure pre-branched cable, comprise main cable, branch cable, branched connection members, branch's connector sheath, branch cable connects main cable by branched connection members, described main cable and branch cable are equipped with the cable core of insulated wire cores and inserts stranding, nonwoven fabrics band lapping layer, flame-retardant composite sheath and oversheath, the junction that branch's connector sheath is wrapped in main cable and branch cable is peripheral, described insulated wire cores is formed by aluminium alloy conductor extruding crosslinked polyetylene insulated layer, described flame-retardant composite sheath is made up of oxygen barrier layer and flame retardant coating two parts, described oversheath is extruded on flame-retardant composite sheath by flame-proof polyvinyl chloride or low smoke halogen-free flame-retardant polyolefin, described branched connection members is made up of aluminum alloy material, the aluminum alloy material of branched connection members is identical with the aluminium alloy conductor material of branch cable with main cable.
The junction that described branch connector sheath is wrapped in main cable and branch cable by the injection moulding of low-smoke non-halogen flame-retardant clean type injection molding material is peripheral.
Described inserts is PP gasket for packing or alkali-free glass wool gasket for packing.
Described aluminium alloy conductor forms by aluminium alloy single line is stranded.
Described crosslinked polyethylene is crosslinked polyethylene after warm water crosslinking or vapor crosslinking.
the utility model is rational in infrastructure,have employed structural design and the new diseases of innovation, the aluminium alloy conductor that cable conductor adopts aluminium alloy single line stranded, product has good electric conductivity and mechanical performance, integrated cost is cheap, branch's connecting piece material adopts the aluminum alloy material consistent with cable conductor, there is primary cell phenomenon when preventing fixture to be connected with conductor, effectively extend the useful life of cable.
Adopt crosslinked polyethylene as cable insulation material, there is good insulation property, heat-resistant stability after warm water crosslinking or vapor crosslinking and cross heat aging performance, and thermal shock when can stand high-temperature injection and not being destroyed.
Inserts adopts PP gasket for packing or alkali-free glass wool gasket for packing, and alkali-free glass wool belongs to non-combustible matter, can not burn, and while playing cable filling, increases fire resistance.
Flame-retardant composite sheath, be divided into oxygen barrier layer and flame retardant coating, oxygen barrier layer adopts environmental protection clean type high flame retardant material to extrude and forms, and the oxygen barrier layer extruded can encase cable core closely, plays sealing function to cable core, and surfacing is smooth, without the Bamboo-shaped produced time wrapped, improve cable surface presentation quality, and flame retardant coating heat crust, stop that flame enters cable inside, strengthen the ability of cable resistant to mechanical damage.If when breaking out of fire, when oxygen barrier layer is by flame baking, flame retardant in oxygen barrier layer produces crystallization, play the effect of cooling on the one hand, on the other hand the crystallization water can deposit seed material, oxygen barrier layer plays the effect of isolation oxygen, and reach fire-retardant object, fire resistance reaches the flame-retardancy requirements specified in GB/T19666.For having the elastomeric material of processability under flame retardant coating normality, the hardening crust of heat, have the features such as high temperature resistant, mechanical resistant collision after crust, as stopped when fire occurs, flame and weight are to the damage of cable internal structure, ensure the normal power supply of cable.
Branch's union body sheath adopts low-smoke non-halogen flame-retardant clean type injection molding material, the connected body smooth surface of injection moulding, and material is not halogen-containing, harmful gas and material is not produced during burning, printing opacity power is high, and be conducive to withdrawing of personnel and object, environment does not cause secondary to endanger yet.Meanwhile, this structure also according to client's needs, can optionally add flame-retardant composite sheath structure.
Jacket material have employed the low-smoke halogen-free polyolefin protective cover material of environment-protecting clean, during this material combustion the amount of being fuming little, do not produce the hydrogen halide be pernicious to people, environment is not caused and directly pollutes and secondary pollution, belong to green material.Can be applicable to the places that crowd is relatively intensive, security higher grade such as skyscraper, public place of entertainment, factory, hospital.
