Abstract
The invention discloses a medium-voltage fireproof power cable for coal mine. The power cable comprises an outer sheath layer and three groups of copper core compacted twisted conductive cores; and the three groups of copper core compacted twisted conductive cores are arranged inside the outer sheath layer. According to the invention, the power cable has the excellent physical and chemical performances and is suitable for the underground complex environment. The cable has the certain flame-retardant performance; and when the cable burns, a ceramic housing is generated to block contact of the inside of the cable with the air, thereby protecting the circuit safety.
Description
Technical field
The present invention relates to coal mine cable equipment technical field, specifically a kind of colliery with in press fireproof power cable.
Background technology
Along with the development in epoch, the production safety in colliery more and more comes into one's own.In the coal mining accident in China's past, gas, water and fire are all the main inducing of China's coal-mine accident, wherein because the accident of gas explosion is particularly outstanding, reach percent 47 of coal mining accident sum.Therefore the cable used within coal mines, all needs very high technical requirement.
