Abstract
The invention discloses a novel high flame retardancy fireproof medium voltage power cable, which can be used for medium voltage power transmission system having a rated voltage in a range from 6kV to 35kV, and can be used for occasions having a high requirement on fireproof performance. The novel high flame retardancy fireproof medium voltage power cable comprises conductors, which are provided with insulation layers. The insulation layers are, from inside to outside, sequentially provided with a flame retardancy filling layer, a fireproof layer, a high flame retardancy isolation layer, a high flame retardancy fireproof coating armoring layer, and a high flame retardancy outer protection layer. The flame retardancy filling layer, the fireproof layer, the high flame retardancy isolation layer, and the high flame retardancy outer protection layer are provided. The novel high flame retardancy fireproof medium voltage power cable is advantageous in that the integrity of the cable in the temperature range from 1000 DEG C to 3500 DEG C can be guaranteed, and at the same time, the spreading of the fire can be effectively reduced, and the power transmission can be guaranteed.
Description
Technical field
The present invention relates to a kind of for rated voltage 6-35kV medium-voltage power-transmission system, fire resistance requires high occasion.
Background technology
The fire-resistant medium-pressure power cable of this novel high flame retardant is used for rated voltage 6-35kV medium-voltage power-transmission system, and fire resistance requires high occasion.Traditional fire-resistant medium-pressure power cable comprises conductor, insulating barrier, screen, fire-retardant lapping layer, inner cushion layer, armour and fire-retardant outer jacket, the further combustion of the intensity of a fire can be stoped to prolong when ordinary circumstance temperature reaches 750 DEG C, but 1000 DEG C so that reach 3500 DEG C temperature under, shield sleeve flame and this protection of flame retardant coating just lose the effect of electric energy transmitting, and the fire-resistant medium-pressure power cable of this novel high flame retardant be exactly 1000 DEG C so that reach 3500 DEG C temperature under ensure the integrality of cable, can effectively reduce spreading of the intensity of a fire simultaneously, ensure the transmission of electric energy.
Summary of the invention
For the above-mentioned deficiency existing for prior art, technical problem to be solved by this invention is to provide the fire-resistant medium-pressure power cable of a kind of novel high flame retardant, and it effectively in case of fire, can ensure the integrality of circuit, ensures the fail safe of delivery of electrical energy.
In order to solve the problems of the technologies described above, the fire-resistant medium-pressure power cable of novel high flame retardant of the present invention, its structure is conductor, conductor has insulation, walking insulation is flame resistant filler layer, flame retardant coating, high flame retardant separator, High-flame-retardancfireproof fireproof coating armour, high flame retardant outer jacket from the inside to surface successively, flame resistant filler layer, flame retardant coating, high flame retardant separator, high flame retardant outer jacket.
After adopting said structure; key is that flame retardant coating adopts fireproof Ceramic silicon rubber composite band at 590 DEG C ~ 3500 DEG C temperature;, housing of complete hard by Low fire ceramic shape rapidly; hard housing armouring after burning plays a very good protection to circuit, ensures circuit in case of fire unimpeded.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the fire-resistant medium-pressure power cable of a kind of novel high flame retardant of the present invention is described in further detail.
Fig. 1 is the structural representation of the fire-resistant medium-pressure power cable of high flame retardant of the present invention with embodiment.
In figure, 1-conductor, 2-insulation, the fan-shaped packing of 3-high flame retardant, 4-Ceramic silicon rubber composite band flame retardant coating, 5-high flame retardant separator, 6-High-flame-retardancfireproof fireproof coating armour, 7-high flame retardant outer jacket.
Embodiment
1 conductor shown in Fig. 1 extrudes insulating barrier 3, then 3 insulated wires carry out strand systems, form cable core, in cable core gap, replace fire-retardant PP reticulate pattern strips with the packing 3 of the fan-shaped high flame retardant with special shape, the consistency in such guarantee cable footpath, structure is rounding more.Flame retardant coating is formed at cable core outer cladding two-layer ceramic SiClx rubber composite belt 4, Ceramic silicon rubber fireproof take-up strap is at 590 DEG C ~ 3500 DEG C temperature,, housing of complete hard by Low fire ceramic shape rapidly, the hard housing armouring after burning plays a very good protection to circuit, ensures circuit in case of fire unimpeded, density ratio mica tape is low, only have 1.40 ~ 1.50g/cm3, the easy moisture absorption of mica tape, water funk, storage period is short, add and need dry process man-hour, increase processing cost; And composite band do not absorb water, nonhygroscopic, storage period can reach 1 ~ 3 year.This product has white low cigarette, Halogen, without phosphorus nitrogen, heavy metal free, nontoxic, harmless, not melting, does not drip; Flue gas toxity safe class reaches the highest level of security ZA1 level of macromolecular material, can not cause secondary injury, meet environmental requirement to human body.Extrude high flame retardant separator 5 at Ceramic silicon rubber composite band flame retardant coating 4, there is fire-retardant and effect that is waterproof simultaneously.Form High-flame-retardancfireproof fireproof coating armour 6 at the outer wrapped steel band with special fire proofing material of high flame retardant separator 5, finally extrude high flame retardant outer jacket 7 High-flame-retardancfireproof fireproof coating armour 6 is external.Adopt such structure can effectively stop spreading of the intensity of a fire, ensure the integrality of cable, ensure the fail safe of delivery of electrical energy.
