Embodiment Construction

[0017] Such as figure 1 As shown, a low-smoke halogen-free anti-ultraviolet frequency conversion cable, the main core and the protective core located in the gap between the main cores form a cable, and the PP rope 5 filled in the cable gap forms a cable core, and the cable core is wrapped with the first winding in turn. cladding layer 6 , copper wire braided shielding layer 7 , second wrapping layer 8 , copper tape shielding layer 9 , third wrapping layer 10 and low-smoke halogen-free outer sheath layer 11 .

[0018] The main core is composed of a main core conductor 1 and a main core insulating layer 2 wrapped outside the main core conductor 1 .

[0019] The protective core is composed of a protective core conductor 3 and a protective core insulating layer 4 wrapped outside the protective core conductor 3 .

[0020] The second wrapping layer 8 is composed of non-alkali glass cloth tape and polyester tape wrapped outside the non-alkali glass cloth tape.

[0021] The third wr...

Abstract

The invention provides a low-smoke halogen-free ultraviolet-proof variable frequency cable, wherein a cable core is formed with main wire cores, protective wire cores located in the gapes of the main wire cores and PP (Polypropylene) ropes arranged in rest gaps, and orderly covered with a first wrapping layer, a copper braid shielding layer, a second wrapping layer, a copper strip wrapped shielding layer, a third wrapping layer and a low-smoke halogen-free outer sheath layer. Due to the adoption of two layers of shielding structures, the low-smoke halogen-free ultraviolet-proof variable frequency cable is low in transmission impedance and good in outside electromagnetic interference elimination effect, in combination with the design of the second wrapping layer and the third wrapping layer, the noise of a variable frequency motor can be reduced, due to the design of a category soft conductor structure, the cable is enabled to have good bending property, and due to the adoption of the ratproof, anti-ant and ultraviolet-proof low-smoke halogen-free polyolefin sheath, the cable is enabled to have strong environmental resisting capability; besides, the 3+3 cable core structure with three main wire cores and three protective wire cores is stable, compact, and high in resistance to impact of transformer generated impulse voltage.

Description

technical field [0001] The invention relates to a frequency conversion cable, in particular to a low-smoke, halogen-free and anti-ultraviolet frequency conversion cable. Background technique [0002] The existing frequency conversion cables in China are usually ordinary four-core cables, which do not have the ability to resist electromagnetic interference; and the structural stability is relatively poor. After the cable is laid, the damage to the cable caused by rats and ants reduces the safety performance and use of the cable. life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-smoke, halogen-free and anti-ultraviolet frequency conversion cable, which can solve the problem of external electromagnetic drying and noise, can shield external electromagnetic interference, reduce the noise of frequency conversion motor, and enhance the voltage shock resistance and bending performance of the cable and environm...
