Domestic cable is in production, in order to reach flame retardant effect, it will usually the halide containing halogen is added in the sheath of cable
Or metal oxide, but cable easily burns when open fire contact, voltage overload, hot operation, and when burning can also
The toxic gas for releasing stimulation, damages Field Force, so that rescue and fire-fighting work are difficult, while also dirty
Neighbouring environment is contaminated.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of low smoke and zero halogen high-temperature cables, to ensure cable in frame
And if safety and the feature of environmental protection when application.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of low smoke and zero halogen high-temperature cable, including cable core, cable core are coated with inner restrictive coating, and inner restrictive coating is coated with interior
Armor, the inner armor layer are twisted by several armouring wires and equally distributed three temperature-measuring optical fibers, inner armor layer outsourcing
It is covered with thermal insulation layer, being twisted outside thermal insulation layer there are several armouring wires, forms armoured layer, armoured layer is coated with surrounding layer, outside
Covering is coated with external sheath layer, and external sheath layer and inner restrictive coating are low-smoke halogen-free polyethylene material.
The cable core includes inner cladding, is equipped with four inner cores being close to two-by-two in inner cladding, between the inside of four inner cores
And asbestos cord is equipped between outside, the gap inside inner cladding is filled with fire-retardant filler.
The inner core includes conductor, and conductor is coated with insulating layer, and insulating layer is coated with waterstop.
The insulating layer is cross-linking polyethylene materials.
The inner cladding is refractory synthetic mica tape, and fire-retardant filler is glass fibre.
The thermal insulation layer is ceramic fiber band, and surrounding layer is refractory synthetic mica tape.
The utility model has the advantages that：The cable of the utility model is using inside and outside two layers of low smoke and zero halogen polyethylene material as shield
Jacket layer has excellent flame retardant property, while inside and outside armouring wire effectively increases the intensity of cable, and temperature-measuring optical fiber can be real-time
Feedback cable suffered temperature at the scene, so that cable also has preferable anti-interference, safety and ring in application
Guarantor property.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
