The utility model is further arranged to: the quantity of the bearing rope that the inner core includes and the ratio of diversion rope are 2:1.
By using above-mentioned technical proposal, the winding number of share of stock of inner core is three multiple, can have preferable stability
With stronger stress performance, wherein bearing rope quantity is more can keep good load-bearing capacity, and in the feelings of auxiliary load-bearing
Diversion rope can have certain space accounting so that it can keep preferable water absorbing properties under condition.
The utility model is further arranged to: the inner core is made of four bearing ropes and two diversion ropes.
By using above-mentioned technical proposal, the hexagon structure slightly distorted is formed, just has more appropriate expansion empty
Between and compared with high-tensile.
The utility model is further arranged to: the close beginning of the flame-retarding rope and the insulation pack coating of end and resistance
Priming hole is provided through on combustion clad.
By using above-mentioned technical proposal, the water-taking efficiency in impregnation process is improved, reduces the water in practical process
It is natural loss.
The utility model is further arranged to: the thermal insulation fabric is by including nonwoven layer, polyimide layer, glass outside interior cause
Glass fibrous layer and polyester layer are provided with micropore in the glass layer, heat reflection particle are provided in the micropore.
By using above-mentioned technical proposal, the inner side and outer side that insulation pack coating is respectively increased in nonwoven layer and polyester layer is connect
The abrasive resistance of contacting surface, to protect insulating portion, wherein polyimides and glass fibre are provided with heat-proof quality, and common combination adds
Strong heat-proof quality, and micropore is collectively covered to protect the heat reflection particle in micropore with polyester layer, and terylene also has centainly
Fire retardancy, play the role of fire-retardant isolation, and heat reflection particle therein can reflect the heat of a part, to reduce
Heat imports.
The utility model is further arranged to: being provided with high temperature resistant glue-line between the insulation pack coating and inner core.
By using above-mentioned technical proposal, the gap between insulation pack coating and inner core is filled up, and improves and is adhered degree, is mentioned
High structural stability.
The utility model is further arranged to: the inflaming retarding fabric is the acrylic fibers layer for disseminating fire retardant.
By using above-mentioned technical proposal, acrylic fibers have good flame retardant property, and fiber softening temperature is higher and has extremely strong
Light resistance, the influence for aging of being exposed to the sun can be reduced.
In conclusion the utility model has the following beneficial effects:
1, heat conduction velocity is reduced by the way that fire-retardant cooperation is heat-insulated, has been reached with the supply of the water penetration of this and diversion rope certain
Balance, so that the safe cable of this programme is considerably longer than general flame-retarding rope in the time of hot environment adhered to,
High-temperature resistance is strong, and relative to good as the light of core, flexibility using metal；
2, light resistance is strong, can reduce the influence for aging of being exposed to the sun；
3, tensile strength is high, and wear-resisting property is good.
