Abstract
The utility model discloses a single-core waterproof medium-voltage cable which is provided with a conductor wire core, wherein an insulating layer, a water-blocking tape layer and an outer sheath are sequentially coated outside the conductor wire core, and the water-blocking tape layer is a longitudinally-wrapped aluminum-plastic composite tape layer. An inner metal shielding layer is further arranged between the conductor wire core and the insulating layer, and an outer metal shielding layer is further arranged between the insulating layer and the water blocking tape layer. The outer sheath is a polyethylene outer sheath. The utility model has good waterproof effect.
Description
Technical Field
The utility model relates to a single-core waterproof medium-voltage cable.
Background
The characteristics required for cables vary due to the different environments in which single-core medium voltage cabling is installed, with water-resistant cables being the most common. For cables to be wet or immersed in water for a long time, it must possess good radial sealing properties in order to avoid moisture ingress. The conventional means for improving the radial tightness of the cable is to use a water-blocking tape, and the water-blocking effect is not good due to the fact that the water-blocking tape is arranged only.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a single-core waterproof medium-voltage cable with a good waterproof effect.
In order to solve the technical problem, the single-core waterproof medium-voltage cable provided by the utility model is provided with a conductor wire core, wherein an insulating layer, a water-blocking tape layer and an outer sheath are sequentially coated outside the conductor wire core, and the water-blocking tape layer is a longitudinally-coated aluminum-plastic composite tape layer.
As an improvement of the utility model, an inner metal shielding layer is arranged between the conductor wire core and the insulating layer, and an outer metal shielding layer is arranged between the insulating layer and the water blocking tape layer.
As a further improvement of the utility model, the outer sheath is a polyethylene outer sheath.
By adopting the single-core waterproof medium-voltage cable with the structure, the water-blocking tape layer is longitudinally wrapped with the aluminum-plastic composite tape layer, the utilization rate of the effective section can be greatly improved due to the longitudinal form of the water-blocking tape layer, the radial sealing property of the cable is ensured, the waterproof effect is good, and the water-blocking tape layer also serves as a metal shield of the cable; after the inner metal shielding layer and the outer metal shielding layer are further arranged, the shielding effect of the utility model is improved, and meanwhile, the waterproof effect of the utility model is also improved; the outer sheath is a polyethylene outer sheath, the polyethylene is a nonpolar molecular material, and the polyethylene is combined with the aluminum-plastic composite belt for use, so that the waterproof effect of the product can be further improved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic sectional structure of a single-core waterproof medium voltage cable according to the present invention.
Detailed Description
