Abstract
The invention discloses a method for wrapping an inorganic mineral insulated cable. The method includes wrapping a first layer of organic mineral strap or fiber strap in an inorganic mineral strap and fiber strap winding procedure; winding a second layer of inorganic mineral strap or fiber strap in the direction opposite to the wrapping direction of the first layer; and then wrapping subsequent wrapped layers in the same mode. The cable wrapped by the method cannot longitudinally loosen, and the electric insulating performance of the cable is improved.
Description
Technical field
The present invention relates to a kind of manufacturing approach of cable, particularly relate to the wrapped method in the inorganic mineral insulation cable manufacture process.
Background technology
Inorganic mineral insulation cable is a kind of in same metallic sheath, makes insulating barrier by inorganic mineral band, fiber and fabric strip, wrapped single or many cables that stranded copper core forms.It requires under 950 ℃ ~ 1000 ℃ temperature; Voltage is at 500 ~ 750V; Under the condition of electric current 3A, keep 90 minutes cables not breakdown, so this inorganic mineral insulation cable has characteristics such as fire resistant, asepsis environment-protecting; Compare other fireproof cables and have more superiority, have vast market prospect.But this cable is in manufacture process; Because inorganic mineral insulating tape and the thinner thickness of fabric strip own; Reach wrapped that certain insulation thickness must be multi-level, the unidirectional multilayer that traditional wrapped mode adopts is wrapped, is easy to produce the twining package tape longitudinal relaxation and influences the insulation electrical performance.
Summary of the invention
Technical problem to be solved by this invention provides a kind of wrapped method of inorganic mineral insulation cable, adopts the wrapped back of this method cable can not produce longitudinal relaxation, has improved the insulation electrical performance of cable.
The wrapped method of a kind of inorganic mineral insulation cable of the present invention; It may further comprise the steps: in inorganic mineral band and the wrapped operation of fabric strip; Behind wrapped ground floor inorganic mineral band or fabric strip; Second layer lapping direction and ground floor are in the opposite direction, adopt the same manner during wrapped afterwards follow-up lapping layer.
The stack coverage rate of said each layer lapping layer is more than 50%, and the wrapping angle of every layer of inorganic mineral band or fabric strip is 45 °.
Beneficial effect of the present invention:
1, is the stack coverage rate of each layer of insulating tape more than 50%, guaranteed the consistency of insulation.
2, the lapping direction of adjacent two layers is opposite, reduces unidirectional accumulated error.
3, every layer of banded wrapping angle is 45 °, prevents that extending longitudinally from elongating.
Embodiment
The wrapped method of a kind of inorganic mineral insulation cable of the present invention; It may further comprise the steps: in inorganic mineral band and the wrapped operation of fabric strip; Behind wrapped ground floor inorganic mineral band or fabric strip; Second layer lapping direction and ground floor are in the opposite direction, adopt the same manner during wrapped afterwards follow-up lapping layer.The stack coverage rate of said each layer lapping layer is more than 50%, and the wrapping angle of every layer of inorganic mineral band or fabric strip is 45 °.
The concrete application approach of the present invention is a lot, and the above only is a preferred implementation of the present invention, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
Claims (3)
1. the wrapped method of an inorganic mineral insulation cable; It is characterized in that may further comprise the steps: in inorganic mineral band and the wrapped operation of fabric strip; Behind wrapped ground floor inorganic mineral band or fabric strip; Second layer lapping direction and ground floor are in the opposite direction, adopt the same manner during wrapped afterwards follow-up lapping layer.
