Abstract
A novel mineral insulated cable includes three copper twisted wires which are unidirectionally twisted. Each copper twisted wire is coated with a layer of fireproof mica tape outside. The intervals among the three copper twisted wires are filled by alkali-free fiberglasses, and the outside of the three copper twisted wires are coated with an alkali-free fiberglass belting. The outside of the alkali-free fiberglass belting is a corrugating copper sheath. The outside of the corrugating copper sheath adopts an anticorrosion polyvinyl chloride oversheath. The novel mineral insulated cable of the utility model employs the anticorrosion polyvinyl chloride oversheath outside, thus solving the problem of static electricity and insulation. The employment of the alkali-free fiberglass inside the cable can further guarantee the static charge insulation effect.
Description
Technical field
The utility model patent relates to a kind of construction of cable, a kind of specifically novel mineral insulated cable.
Background technology
The inner cable that uses in mine generally need adopt insulation, if not the static that is easy to generate of insulation, causes the problem of catching fire even exploding easily, influences the safety of inside, mine.So provide a kind of insulation effect mineral insulated cable good, that do not produce static necessary.
The utility model content
Based on the problems referred to above, the purpose of this utility model provides a kind of novel mineral insulated cable.
The purpose of this utility model is achieved through the following technical solutions.
Novel mineral insulated cable, three copper stranded conductors that comprise unidirectional winding, the outside of every copper stranded conductor all is coated with one deck fire-resistant isinglass belt, between three copper stranded conductors, adopt alkali-free glass wool to fill, and in the alkali-free glass wool band coating of the outside of three copper stranded conductors, the outside of alkali-free glass wool band is the embossing copper sheath, adopts anticorrosion polyvinyl chloride oversheath in the outside of embossing copper sheath.
The novel mineral insulated cable that the utility model adopts, the anticorrosion polyvinyl chloride oversheath of peripheral employing can solve the problem of static and insulation, and its inner alkali-free glass wool that adopts can further guarantee the effect of electrostatic charge insulation.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structure chart of novel mineral insulated cable described in the utility model.
Embodiment
As shown in Figure 1, novel mineral insulated cable, three copper stranded conductors 1 that comprise unidirectional winding, the outside of every copper stranded conductor 1 all is coated with one deck fire-resistant isinglass belt 2, between three copper stranded conductors 1, adopt alkali-free glass wool 3 to fill, and in usefulness alkali-free glass wool band 4 coatings of the outside of three copper stranded conductors 1, the outside of alkali-free glass wool band 4 is an embossing copper sheath 5, alkali-free glass wool 3 and alkali-free glass wool band 4 can play good insulation effect, embossing copper sheath 5 is given the enough rigid support of whole cable, can prevent that cable is out of shape in receiving the process of extruding, influence the communication effect of cable, adopt anticorrosion polyvinyl chloride oversheath 6 in the outside of embossing copper sheath 5, oversheath 6 can play good insulation and anti-static electrification, is effective assurance of whole cable quality.
The novel mineral insulated cable that the utility model adopts, the anticorrosion polyvinyl chloride oversheath of peripheral employing can solve the problem of static and insulation, and its inner alkali-free glass wool that adopts can further guarantee the effect of electrostatic charge insulation.
