Abstract
The invention provides a flame-retardant and waterproof power line, which comprises a metal conductor (1) as an innermost layer, wherein an insulated durable protection layer (2) surrounds the outside of the metal conductor (1); a polyvinyl chloride layer (3) surrounds the outside of the insulated durable protection layer (2); a braid layer (4) is arranged outside the polyvinyl chloride layer (3); a halogen-free flame-retardant TPEE material layer (5) is arranged outside the braid layer (4); mixed powder of flame retardants Sb2O3 and Mg(OH)2 is evenly added to the inside of the insulated durable protection layer (2); and the mass ratio of the flame retardant Sb2O3 to the flame retardant Mg(OH)2 is 3 to (5-9). The flame-retardant and waterproof power line has the advantages of high insulating property and good antiseptic property; and most importantly, the water-proof capability, the flame-retardant property and the like are relatively greatly improved.
Description
Technical field
The present invention relates to power line cables technical field, be specifically related to a kind of fire-resistant waterproof power line.
Background technology
Traditional single-core line of the prior art, along with meeting quick aging service life, and be easy to destroy internal structure, cause the fracture of internal core, and 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 serious.
Summary of the invention
The object of the present invention is to provide a kind of fire-resistant waterproof power line, 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 fire-resistant waterproof power line, described power line comprises the metallic conductor (1) of innermost layer, surround one deck outward at described metallic conductor (1) to insulate durable protective layer (2), one deck polyvinyl chloride layer (3) is surrounded outward at the durable protective layer of described insulation (2), the durable protective layer of described insulation (2) comprises following three layers: TPU and EVA composite environmental-friendly wearing layer (21) from inside to outside successively, what be close to described TPU and EVA composite environmental-friendly wearing layer is reinforced layer (22), what be close to described reinforced layer is watertight composition (23), described reinforced layer is glass layer, and the tensile strength of described glass fibre is 5000-5100Mpa, outside described polyvinyl chloride layer (3), be provided with one deck braid (4), outside described braid (4), have one deck halogen-free flameproof TPEE material layer (5).Fire retardant Sb is evenly added with in the durable protective layer of described insulation (2)

2o
3with Mg (OH)
2mixed powder, described fire retardant Sb
2o
3with Mg (OH)
2mass ratio be 3:5, 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.
