Abstract
A low-smoke and halogen-free temperature-resistant environment-friendly and energy-saving power cable with a polyethylene insulated polyolefine sheath comprises a metal conductor arranged at the center, an insulating layer, stuffing and a sheathing layer. The power cable is characterized in that a flame-retarding oxygen-isolating band(4) and a galvanized steel strip(5)are arranged between the insulating layer and the sheathing layer(6) of the cable; the insulating layer adopts low-smoke and halogen-free radiation crosslinked material, particularly 125 DEG C radiation crosslinked material; the flame-retarding oxygen-isolating band(4) adopts halogen-free flame-retarding glass fiber tapes; and the sheathing layer(6) adopts 105 DEG C sheathing material. High temperature resistance of the power cable is improved by a large margin, from the commonly 75 DEG C to 125 DEG C, which means that the current carrying capacity of a cable with the same section area is improved, or that the cost of a cable with the same current carrying capacity is greatly reduced. Meanwhile, the power cable is totally made of low-smoke and halogen-free environment-friendly material, so the environment protection performance and safety of the power cable are greatly improved.
Description
Technical field
The utility model relates to power cable, is a kind of polyethylene insulation polyolefin jacket low smoke and zero halogen heatproof environmental protection and energy saving power cable specifically.
Background technology
For power cable, its current capacity is only considered the sectional area of conductor thread core usually, this is because the electric current increase can make conductor temperature raise, and the insulating barrier that an implied condition is arranged here is the conductor outsourcing can only bear 75 ℃ usually, and good material can reach 90 ℃.The words that temperature surpasses the upper limit can cause the change on the insulating barrier generation performance, and insulating reliability greatly reduces, and higher temperature can cause insulating barrier emerge poisonous dense smoke even burning.This poisonous dense smoke is called halogen gas, is that power line burning back produces the principal element of fatal harm.
Summary of the invention
The purpose of this utility model provides a kind of polyethylene insulation polyolefin jacket low smoke and zero halogen heatproof environmental protection and energy saving power cable that can improve the power cable current capacity and have fire-retardant, low cigarette, nontoxic performance.
Described polyethylene insulation polyolefin jacket low smoke and zero halogen heatproof environmental protection and energy saving power cable comprises it is characterized in that metallic conductor, insulating barrier, inserts, the restrictive coating at center: this cable also has oxygen-barrier zone and galvanized steel strip between insulating barrier and restrictive coating; Described insulating barrier adopts low smoke and zero halogen cross-linking radiation material, and model is 125 ℃ of cross-linking radiation material, and described oxygen-barrier zone adopts halogen-free flameproof glass fabric strip material, and it is 105 ℃ of protective cover materials that restrictive coating adopts the raw material model.
Described metallic conductor can be copper, aluminium or copper-covered aluminum-core.
The utility model has significantly improved the heat-resisting ability of cable, bring up to 125 ℃ by common 75 ℃, its current capacity of cable that is equivalent to same sectional area is improved, its cost of cable of same current capacity has obtained significantly reducing in other words, this cable has also all adopted the low smoke and zero halogen environment-friendly materials simultaneously, and its environmental protection, security performance have all obtained very big lifting.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-conductor, 2-insulating barrier, 3-inserts, 4-oxygen-barrier zone, 5-galvanized steel strip, 6-restrictive coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: polyethylene insulation polyolefin jacket low smoke and zero halogen heatproof environmental protection and energy saving power cable as shown in fig. 1, comprise metallic conductor, insulating barrier, inserts, the restrictive coating at center, it is characterized in that: this cable also has oxygen-barrier zone 4 and galvanized steel strip 5 between insulating barrier 2 and restrictive coating 6; Described insulating barrier 2 adopts low smoke and zero halogen cross-linking radiation material, and model is JLS-FR125, and described oxygen-barrier zone 4 adopts halogen-free flameproof glass fabric strip material, and it is JLS-FR105H that restrictive coating 6 adopts the raw material model.Described metallic conductor can be copper, aluminium or copper-covered aluminum-core.
Because insulating barrier 2 adopts 125 ℃ of cross-linking radiation material, its resistance to elevated temperatures rises to 125 ℃, also possesses the environmental-protecting performance of low smoke and zero halogen simultaneously.And the normally used insulating layer material heatproof upper limit only can reach 75 ℃ or 90 ℃.These insulating barrier 2 materials have the low smoke and zero halogen performance simultaneously, possess good pliable and tough ductility after cross-linking radiation is handled.
Make whole cable possess high temperature resistant and the low smoke and zero halogen performance, also need inserts 3, oxygen-barrier zone 4, restrictive coating 6 also to possess high temperature resistant and the low smoke and zero halogen environmental-protecting performance.Wherein restrictive coating 6 employing raw material models are 105 ℃ of protective cover materials of JLS-FR105H, and except that having the low smoke and zero halogen performance, its heatproof reaches 105 ℃, and the heatproof of restrictive coating only reaches 75 ℃ usually.
Heat-resisting ability improves its current capacity of cable that is equivalent to same sectional area and is improved, its cost of cable of same current capacity has obtained significantly reducing in other words, this cable has also all adopted the low smoke and zero halogen environment-friendly materials simultaneously, and its environmental protection, security performance have all obtained very big lifting.Excessive in conductor current, this product had low cigarette, Halogen and high flame retardant characteristic when temperature was too high, and the utility model cable can guarantee that still normal power supply is more than 180 minutes under 750 ℃～800 ℃ burning conditions.
