Description
Technical field
This utility model belongs to type low-voltage cable technical field, is specifically related to a kind of environmental protection interlocking armour fireproof cable.
Background technology
In social life, fire is one of disaster threatening public safety, harm people's lives and properties, and it brought many life and the heavy losses of property to human society.Along with the development of social productive forces, the wealth of society increases day by day, and fire damage and damaging range thereof are also expanding.Fire is a kind of disaster that in the world today, in multiple disaster, occurrence frequency is higher, is also a kind of disaster of space-time span maximum.Fire is the common wicked problems that the people of other countries are faced,
When fire occurs, people require time for escape, rescue important goods and materials and archives, stop large-size reactor and the physical-chemical reaction etc. of nuclear power plant reactor, thus it requires in the place that the crowd is dense, the elevator of high building, power supply and the control cable of the key occasions such as physical reaction control system use fire-resistant wire and cable.
So-called fire-resistant wire and cable, it is simply that in the case of being in flame combustion, it is possible at a higher temperature, within the time of regulation, keeps the electric wire of normal electric power or signal transfer functions.
Fire-resistant wire and cable to pass through fire resistance test by standard.At present, domestic and international fire-resistant wire and cable generally uses two kinds of structures:
One is mica tape fire-resisting cable: i.e. which floor mica tape wrapped on the conductor of electric wire, extruded insulation layer again outside mica tape, as the hot-face insulation core of fire-resistant wire and cable, core stranding again (adds shielding, armouring etc.) if desired, extrude sheath, make fire-resisting cable.
Another kind is mineral insulation fire-resisting cable: its elastic refractory insulating layer uses oxidation joy powder to be extruded from, and i.e. puts on honeycomb coaly oxidation steamed bun on several cable conductors, and outsourcing copper strips is also welded into pipe, then be drawn into fire-resisting cable.
Above two cable is respectively arranged with pluses and minuses:
The advantage of mica tape fire-resistant wire and cable is soft: can make long length, small bore: equipment is simple, and shortcoming is that insulated wire cores needs wrapped mica tape and extruded insulation two procedures: core external diameter increases: be only used for typically requiring fire-resistant occasion.
The advantage of mineral insulation fire-resisting cable is that fire resistance is good, may be used for the important place high to fire resistant requirements.Shortcoming is that technology difficulty is big, needs special equipment, equipment mostly to be import: cable is harder, the most flexible, if need to turn little curved during installation, need to carry out special disposal: length can not be the longest, to the longest, subsequent process is more complicated: can not do small bore fire-resistant wire and cable.
