Description
Technical field
The utility model belongs to power cable field, and in particular to high insulation resistance flexible fire-proof cable easy to install.
Background technique
In real life, short circuit it is on fire be cause fire a big key factor, therefore, power cable it is fire-retardant
Fire protecting performance is directly related to the security of the lives and property, and common power cable has insulating properties and often do not prevent fires, and special
Although fireproof cable can reach certain requirement in fire protecting performance, often quality is harder, flexible poor, applies in practical lay
It is extremely inconvenient in work, therefore can not also choose at random safer path, it is easy that there are security risks.
Summary of the invention
In view of the deficienciess of the prior art, the utility model provides high insulation resistance flexible fire-proof cable easy to install.
The utility model is achieved through the following technical solutions:
High insulation resistance flexible fire-proof cable easy to install, including cable core, the cable core it is twisted by several insulated wire cores and
At the insulated wire cores are made of conductor and Ceramic silicon rubber insulating layer, and the ceramic SiClx is extruded on the outside of the conductor
Rubber insulation, the cable core outside are extruded with one layer of inner sheath, and the inner sheath lateral gap is around galvanized steel strip group of double-baging
At armor, oversheath is extruded with outside the armor.
The Ceramic silicon rubber insulating layer uses Ceramic silicon rubber.
The inner sheath is that thermoplastics type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
The galvanized steel strip that the armor uses is hot-galvanized steel band.
The oversheath is that heat curing type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
Compared with prior art, the utility model has the beneficial effects that the utility model is insulated using Ceramic silicon rubber
Layer, the more common insulating layer of layer fire prevention feature with higher, and relatively economical；Inner sheath uses thermoplastics type's LSOH anti-flaming
Polyolefin jacket, oversheath is halogen-free and low-smoke flame-retardant polyolefin sheathed using heat curing type, and surface is smooth, good insulation preformance, mechanicalness
It can be excellent, ageing-resistant；Armor is wrapped by two layers of hot-galvanized steel band gap, guarantees the flexibility of cable, safer convenient for choosing
Path carries out installation, while lifting construction efficiency, reduces security risk.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
In attached drawing: 1. cable cores；2. core；3. conductor；4. Ceramic silicon rubber insulating layer；5. inner sheath；6. armor；7.
Oversheath.
Specific embodiment
Such as the embodiment that Fig. 1 is shown in Figure of description, high insulation resistance flexible fire-proof cable easy to install, including cable core
1, cable core 1 is twisted by three insulated wire cores 2, and insulated wire cores 2 are made of conductor 3 and Ceramic silicon rubber insulating layer 4, conductor
3 outsides are extruded with Ceramic silicon rubber insulating layer 4, one layer of inner sheath 5 are extruded on the outside of cable core 1,5 lateral gap of inner sheath is wrapped
Two layers of galvanized steel strip forms armor 6, and oversheath 7 is extruded with outside armor 6.
Further, Ceramic silicon rubber insulating layer 4 uses Ceramic silicon rubber, and Ceramic silicon rubber insulating layer 4 is one
Kind silicon rubber is that substrate is added into special silicone rubber fireproof high-temperature resistant material made of porcelain auxiliary agent and various functional fillers.
Further, inner sheath 5 is that thermoplastics type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
Further, the galvanized steel strip that armor 6 uses is hot-galvanized steel band.
Further, oversheath 7 is that heat curing type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
