CN203644427U - Crosslinked polyethylene insulating halogen-free low-smoke anti-mouse anti-ant polyolefin sheath flame-retardant cable - Google Patents

Abstract

The utility model discloses a crosslinked polyethylene insulating halogen-free low-smoke anti-mouse anti-ant polyolefin sheath flame-retardant cable. The crosslinked polyethylene insulating halogen-free low-smoke anti-mouse anti-ant polyolefin sheath flame-retardant cable is characterized in that a plurality of control conductors and a main conductor are stranded, and then a fiber band tensile lapping layer coated with a semi-conductive colloid, a glass silk fireproof layer and a tinned copper wire braided layer are wrapped on the outsides of the stranded control conductors and the main conductor orderly to form a control wire core; a plurality of power conductors and placed according to a fan-shape, and then an aluminum plastic composite belt lapping layer is wrapped on the outsides of the fan-shaped power conductors to form a power wire core; two control wire cores and two power wire cores are placed at the four corners of a cross-shaped rubber skeleton at intervals, a low-smoke and halogen-free polyvinyl chloride insulating layer, a steel wire braided shielding layer, a high strength polyester silk braided reinforcing layer and a halogen-free low-smoke anti-mouse anti-ant polyolefin flame-retardant sheath are wrapped on the outside of the cross-shaped rubber skeleton orderly, and adhesion agents are coated at the four end parts of the cross-shaped rubber skeleton separately. The crosslinked polyethylene insulating halogen-free low-smoke anti-mouse anti-ant polyolefin sheath flame-retardant cable of the utility model is good in insulating and shielding properties, guarantees a good flame retardant property, can prevent the mouse and ant from biting the cable, and enables the service life to be prolonged.

Description

Crosslinked polyetylene insulated low smoke, zero halogen rat-and-ant proof polyolefin jacket flame retardant cable

Technical field

The utility model relates to cable technology field, relates in particular to a kind of crosslinked polyetylene insulated low smoke, zero halogen rat-and-ant proof polyolefin jacket flame retardant cable.

Background technology

, often there is the mouse ant moth erosion cable situation that bites in the occasion of often haunting in muroid and the concentrated area of humid tropics termite, causes cable water inlet or make moist, and causes the accidents such as power failure, communicating interrupt, serious short circuit, fire, brings immeasurable loss.

Utility model content

The utility model object is exactly the defect in order to make up prior art, and a kind of crosslinked polyetylene insulated low smoke, zero halogen rat-and-ant proof polyolefin jacket flame retardant cable is provided.

The utility model is achieved through the following technical solutions:

A kind of crosslinked polyetylene insulated low smoke, zero halogen rat-and-ant proof polyolefin jacket flame retardant cable, include leading body, control conductor and power conductor, at leading body, control conductor and the external side of power guide and be all surrounded by polyethylene layer, multiple control conductors and the stranded rear outside of leading body are coated with to the fabric strip tension lapping layer that scribbles semiconductive colloid successively, glass fiber fireprotection layer and tincopper fuse wire braided armor form controls core, multiple power conductors are surrounded by aluminium-plastic tape lapping layer by fan-shaped placement and in outside and form power core, by on four angles that are placed on cross rubber skeleton at two control cores and two power core intervals, and be coated with successively low smoke and zero halogen polyvinyl chloride insulation layer in the outside of cross rubber skeleton, braided steel wire screen, high tenacity polyester fiber silk braiding reinforced layer and low smoke, zero halogen rat-and-ant proof polyolefin fire retardant jacket, four ends at cross rubber skeleton scribble respectively adhesion agent.

The utility model has the advantages that: the utility model is provided with cruciform skeleton, and be provided with circular core and the fan-shaped power core controlled, novel structure, insulation shielding performance is good, low smoke, zero halogen rat-and-ant proof fire retardant jacket has ensured that cable has good fire resistance, and can prevent that mouse ant stings bad cable, increases the service life.
