Abstract
The utility model belongs to the wire appliance technical field, and especially relates to a co-extrusion single core wire. The utility model discloses the co-extrusion single core wire, which comprises leads, a protective coating is coated at the external part of the lead, and a heatproof layer is coated on the external part of the protective coating. According to the co-extrusion single core wire, in the prior art, a PVC layer with heatproof grade of 70 DEG is employed, a PVC layer with heatproof grade of 68 DEG is used for the inner part of the co-extrusion single core wire, and the PVC layer with heatproof grade of 70 DEG is only used for the external part. The wire appliance technical field has the advantages of simple structure and low cost, and can reach the civil usage requirements.
Description
Technical field
The utility model belongs to electric wire apparatus technical field, relates in particular to a kind of co-extrusion single-core line.
Background technology
Along with the development of society, the range of application of electric wire more and more widely, especially general civilian electric wire.At present, the civilian electric wire of use has adopted lead outer wrap one deck heat-resistant layer generally all is that heat-resistant layer is that temperature resistant grade is the PVC layer of 70 degree.Belong to reasonable thermal insulation material because temperature resistant grade is the PVC layer of 70 degree, so more expensive on cost, for being applied in civilian going up, cost is higher.
Summary of the invention
The purpose of the utility model is to solve above-described technical problem, and a kind of co-extrusion single-core line is provided, and its technical scheme is following:
A kind of co-extrusion single-core line comprises lead, and the external packets of described said lead is wrapped with an overcoat, and the external packets of said overcoat is wrapped with one deck heat-resistant layer.
Optimal way is that described overcoat is that temperature resistant grade is the PVC layer of 68 degree.
Optimal way is that described heat-resistant layer is that temperature resistant grade is the PVC layer of 70 degree.
The co-extrusion single-core line that the utility model provides, former all is that temperature resistant grade is the PVC layer of 70 degree, and it is that the PVC layer of 68 degree replaces that temperature resistant grade has been used in inside, and just externally having adopted temperature resistant grade is the 70 PVC layers of spending.The utility model is simple in structure, and cost is lower, and can well reach civilian instructions for use.
Description of drawings
The sketch map of Fig. 1 the utility model.
Embodiment
Specify embodiment below in conjunction with Fig. 1:
A kind of co-extrusion single-core line comprises lead 1, and the external packets of described said lead 1 is wrapped with an overcoat 2, and the external packets of said overcoat 2 is wrapped with one deck heat-resistant layer 3.
Optimal way is that described overcoat is that temperature resistant grade is the PVC layer of 68 degree.
Optimal way is that described heat-resistant layer is that temperature resistant grade is the PVC layer of 70 degree.
Claims (3)
