Description
Technical field
The utility model relates to power domain, is specially a kind of cable.
Background technology
At present, known normal cable does not have fire resistant performance.In case of high temperature occasion uses, cannot meet the demands, cannot use.But the cable used in the case of a high temperature, proposes very high requirement to the resistance to elevated temperatures of cable.The heat of cable comes from two aspects, and one is conductor self-heating.Another is the ambient environment of Exterior cable.Existing cable fire resistance is lower.
Summary of the invention
The object of the present invention is to provide a kind of cable, fire resistance is good.
The technical solution of the utility model:
A kind of cable, comprising: copper core; Described copper core is twisted to connect by several copper wire and is formed, and is coated with internal shield in the outside of copper core; Inner insulating layer is coated with outside described copper core; Outer shielding layer is surrounded with outside described inner insulating layer; External insulation layer is coated with outside described outer shielding layer; The thermal insulation layer of establishment is provided with outside described external insulation layer; Wire netting overcoat is surrounded with outside described thermal insulation layer; Fire-proof insulation sheath is surrounded with outside described wire netting overcoat.
Effect of the present utility model:
1, the utility model cable is that sandwich construction is arranged, and structure is simple, easy to use.
2, the thermal insulation layer of the utility model cable adopts glass fiber or mica tape braiding, and its high temperature strength is large.
3, the utility model adopts stainless steel wire braiding to form, and good toughness, shield effectiveness is strong.
Accompanying drawing explanation
Fig. 1 is this novel overall structural representation.
