Abstract

The utility model relates to the field of cable equipment, and in particular to a low-voltage water-proof and moisture-proof flexible cable, which comprises conductors, water blocking yarns stranded with the conductors, an insulating layer wrapped outside the conductors and the water blocking yarns, and an outer sheath wrapped on the outermost layer of the cable. The low-voltage water-proof and moisture-proof flexible cable is characterized in that the cable further comprises water-blocking filling ropes, a water-blocking wrapping tape, an aluminum-plastic composite tape and a PVC inner sheath; the water-blocking filling rope is arranged outside the insulating layer; the water-blocking wrapping tape is wrapped outside the water-blocking filling ropes; the aluminum-plastic composite tape is wrapped outside the water-blocking wrapping tape; the PVC inner sheath is wrapped outside the aluminum-plastic composite tape; and the outer sheath is wrapped outside the PVC inner sheath. According to the utility model, the cable has excellent longitudinal and radial water-proof and moisture-proof performances and the bending performance of the cable cannot be affected due to the adoption of the said design and the cooperation between protection of the multiple layers of water blocking yarns and PVC and aluminum-plastic sheathes.

Description

The waterproof and dampproof flexible cable of low pressure

Technical field

The utility model relates to the cable machinery field, is specially the waterproof and dampproof flexible cable of a kind of low pressure.

Background technology

Traditional waterproof and dampproof cable because its structure, material problem so that water-proof cable vertically, radially waterproof ability is average, in the situation of long-time bending, setting, the useful life of waterproof and dampproof cable is short.

Summary of the invention

The purpose of this utility model is to overcome the defective of existing conventional waterproof moisture resistant cable, provide a kind of novel structure, vertically, the waterproof and dampproof flexible cable of low pressure of strong, the long service life of waterproof ability radially.

In order to achieve the above object, the utility model is achieved in that

The waterproof and dampproof flexible cable of a kind of low pressure, it comprise conductor, with the stranded water blocking yarn of conductor, be wrapped in the outer insulating barrier of conductor, water blocking yarn, be wrapped in the outermost outer protective sleeve of cable, also comprise the gasket for packing that blocks water, the twining package tape that blocks water, aluminium-plastic tape and PVC inner sheath; The gasket for packing that blocks water is located at outside the insulating barrier, and the twining package tape that blocks water is wrapped in outside the gasket for packing that blocks water, and aluminium-plastic tape is wrapped in outside the twining package tape that blocks water, and the PVC inner sheath is wrapped in outside the aluminium-plastic tape, and outer protective sleeve is wrapped in outside the PVC inner sheath.

The waterproof and dampproof flexible cable of described low pressure, aluminium-plastic tape are the double-sided aluminum plastic composite band that vertically coats.

The utility model adopts above-mentioned design, and the protection of multiple water blocking yarn cooperates the sheath of PVC, plastic-aluminum material so that cable have excellent vertically, radially waterproof and dampproof performance, do not affect the bendability of cable simultaneously.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below further specify the utility model by specific embodiment.

As shown in Figure 1, the waterproof and dampproof flexible cable of a kind of low pressure, it comprises conductor 2, the water blocking yarn 3 stranded with conductor 2, be wrapped in the insulating barrier 4 outside conductor 2, the water blocking yarn 3, be wrapped in the outermost outer protective sleeve 1 of cable, also comprise the gasket for packing 5 that blocks water, the twining package tape 6 that blocks water, double-sided aluminum plastic composite band 7 and modified PVC inner sheath 8; The gasket for packing 5 that blocks water is located at outside the insulating barrier 4, the twining package tape 6 that blocks water is wrapped in outside the gasket for packing 5 that blocks water, double-sided aluminum plastic composite band 7 vertically is wrapped in outside the twining package tape 6 that blocks water, and modified PVC inner sheath 8 is wrapped in outside the double-sided aluminum plastic composite band 7, and HDPE outer protective sleeve 1 is wrapped in outside the modified PVC inner sheath 8.

The utility model adopts above-mentioned design; the protection of multiple water blocking yarn cooperates the protection of modified PVC inner sheath, double-sided aluminum plastic composite band, HDPE oversheath; so that cable have excellent vertically, radially waterproof and dampproof performance; simultaneously do not affect the bendability of cable yet, thereby overcome the defective that conventional waterproof moisture resistant cable useful life is short, waterproof ability is average.
