Description
Technical Field
The utility model relates to a control cable technical field specifically is a novel there is not steamed low fire-retardant B1 level control cable of cigarette.
Background
A control cable is a power or signal transmission device, and is usually composed of several wires or groups of wires.
Along with people's environmental awareness increases, there is not steamed low fire-retardant B1 level control cable of cigarette that lacks, there is not all halogen in the used material of steamed low fire-retardant B1 level control cable of cigarette exactly the product, the corrosivity of combustion product is very low with the smog that produces, there is not steamed low fire-retardant B1 level control cable of cigarette inevitably can receive external dragging in the use, disconnected core broken string appears easily, influence the use of steamed low fire-retardant B1 level control cable of cigarette that lacks, therefore, need a novel steamed low fire-retardant B1 level control cable of cigarette that lacks.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel there is not steamed low fire-retardant B1 level control cable of cigarette to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel there is not steamed low fire-retardant B1 level control cable of cigarette, includes around the covering, be equipped with the filler around the covering inside, be equipped with three group's conductors in the filler, the conductor outer wall is equipped with the insulating layer, insulating layer outer wall is equipped with the internal shield layer, be equipped with the external shielding layer around the covering lateral wall, the external shielding layer lateral wall is equipped with the stretch-proofing layer, be equipped with multiunit elastic rib in the stretch-proofing layer, the elastic rib lateral wall is equipped with two sets of strengthening ribs, the stretch-proofing layer lateral wall is equipped with at a distance from the oxygen layer, it is equipped with the oversheath to separate the oxygen layer lateral wall.
Furthermore, the elastic ribs are distributed in the stretch-proofing layer in an annular array mode, one end of each elastic rib is connected with the outer side wall of the outer shielding layer, and the other end of each elastic rib is connected with the inner side wall of the oxygen isolation layer.
Furthermore, the reinforcing ribs are longitudinally arranged, and the two groups of reinforcing ribs are respectively positioned on two side walls of the elastic rib.
Further, the conductor is a tinned copper wire.
Furthermore, the wrapping layer is a halogen-free high-stop band.
Further, the filler is inorganic paper ropes.
Further, the outer sheath is halogen-free high-resistance fuel.
Compared with the prior art, the beneficial effects of the utility model are that: this practicality is for there being not steamed high stop band around the covering, and the oversheath is for there being not steamed high resistant fuel to the corrosivity of control cable combustion products and the smog of production are very low, improve control cable's stretch-proofing performance under the effect of stretch-proofing layer, elasticity muscle and strengthening rib, thereby control cable can not appear the condition of disconnected core broken string when receiving the external world and dragging, improves control cable's life.
