Abstract
The invention provides a durable electric wire. The electric wire comprises a metallic conductor (1) which is arranged in the innermost layer. A layer of insulating durable protective layer (2) wraps outside the metallic conductor (1). A layer of braiding layer (4) is arranged outside the insulating durable protective layer (2). A layer of halogen-free flame-retardant EVA material layer (5) is arranged outside the braiding layer (4). The durable electric wire has high insulating property and great anticorrosion performance, and the most important is that water-resistant and flame-retardant performance is greatly improved.
Description
Technical field
The present invention relates to technical field of electric wires and cables, be specifically related to a kind of durable electric wire.
Background technology
There is single voltage output interface in portable power source of the prior art, namely only provides 5V output interface, its poor universality, can not be applicable to the digital articles for use that charging voltage is different, the shortcomings such as versatility is bad simultaneously.And for 220V power line, also there is many defects, such as cable is given not soft, cable is due to the bad environments of wind power generation, blower fan is longer for service life, and cable constantly rotates with blower fan, higher to the performance requirement of cable, the development and application of wind energy cable also has a lot of difficult point to need to overcome.Be not durable, shaky, antiseptic effect is bad, and especially flame retardant effect difference problem is obvious and serious etc.
Summary of the invention
The object of the present invention is to provide a kind of durable electric wire, have that insulation property are high, antiseptic property good, the performance such as most importantly to block water fire-retardant has the power line of larger improvement.
For realizing object of the present invention, adopt following technical proposal: a kind of durable electric wire, described electric wire comprises the metallic conductor of innermost layer, surround one deck outward at described metallic conductor to insulate durable protective layer, the durable protective layer of described insulation comprises following four layers: TPU Environment-friendlywear-resistant wear-resistant layer from inside to outside successively, what be close to described TPU Environment-friendlywear-resistant wear-resistant layer is reinforced layer, and what be close to described reinforced layer is TPU elastic cord breaker, and what be close to described TPU elastic cord breaker is watertight composition; Described reinforced layer is glass layer, and the tensile strength of described glass fibre is 5000-5100Mpa; Outside the durable protective layer of described insulation, be provided with one deck braid, outside described braid, have one deck halogen-free flameproof EVA material layer.Preferably, fire retardant Sb is evenly added with in the durable protective layer of described insulation
2o
3with Mg (OH)
2mixed powder.
Preferably, the frictional force produced when being evenly added with talcum powder for reducing bending in described braid.
The present invention has the features such as twisting property is good, high water resistant, high flame retardant, uvioresistant and ultra-flexible.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of durable electric wire of the present invention.
Fig. 2 is the cross-sectional view of the durable protective layer of insulation of the present invention.
Embodiment
For understanding the present invention better, be described further below by accompanying drawing:
As shown in Figure 1-2, a kind of durable electric wire, described electric wire comprises the metallic conductor 1 of innermost layer, to insulate durable protective layer 2 at the outer one deck that surrounds of described metallic conductor 1, the durable protective layer of described insulation 2 comprises following four layers: TPU Environment-friendlywear-resistant wear-resistant layer 21 from inside to outside successively, what be close to described TPU Environment-friendlywear-resistant wear-resistant layer is reinforced layer 22, and what be close to described reinforced layer is TPU elastic cord breaker 23, and what be close to described TPU elastic cord breaker is watertight composition 24; Described reinforced layer is glass layer, and the tensile strength of described glass fibre is 5000-5100Mpa; Outside the durable protective layer 2 of described insulation, be provided with one deck braid 4, outside described braid 4, have one deck halogen-free flameproof EVA material layer 5, in the durable protective layer 2 of described insulation, be evenly added with fire retardant Sb
2o
3with Mg (OH)
2mixed powder, when being evenly added with talcum powder for reducing bending in described braid 4 produce frictional force, described braid 4 is tinned copper braids, and metallic conductor 1 presses bare copper conductor.
Although be recognized as a most practical and preferred embodiment to describe the present invention in conjunction with current, but be to be understood that, the invention is not restricted to the disclosed embodiments, and be intended on the contrary contain multiple amendment included in the spirit and scope of the appended claims and equivalent arrangements.
