In May, 2009, State Grid Corporation of China has announced the three step development outlines of China " strong intelligent grid ", has caused the support energetically of several big Power Group.By the end of the year ends 2009, China has carried out the pilot and the demonstration project of all too many levels of intelligent grid, comprising big operation of power networks and safety, intelligent scheduling, digital transformer substation, power distribution automation, user power utilization information management, regenerative resource is incorporated into the power networks and electric motor car charges and discharge emphasis pilot projects such as power station.
Data shows, national grid electric grid investment in 2010 will be about 2,700 hundred million yuan, and the intelligent total investment of building of following electrical network is estimated to reach 4,000 hundred million yuan, and is perhaps more.On link, intelligent grid mainly is distributed in generating, circuit, power transformation, distribution, user with scheduling etc., has guided direction and very strong driving force is provided for investment, has made concrete production programming for corollary equipment manufacturer finds, locatees product accurately." the develop actively intelligent grid has become the new trend of world's electric power development, and to the year two thousand twenty, China will build up unified strong intelligent grid comprehensively." the general manager Liu Zhenya of State Grid Corporation of China represents in " in the 2009 UHV transmission technology international conferences ".He announces externally that simultaneously the target that State Grid Corporation of China builds strong intelligent grid is: electric network coordination development at different levels add, the fast strong intelligent grid of building the unification with informationization, digitlization, automation, interactive feature.Strong intelligent grid is strong reliable, economical and efficient, clean environment firendly, transparent opening, friendly interactive modernized electrical network, comprises key link and information-based support platforms such as generating, transmission of electricity, power transformation, distribution, electricity consumption and scheduling.
In sum, the development of intelligent grid industrial chain will drive the development of intelligent substation, flexible transmission and intelligent scheduling link, for can be supporting intelligent grid accelerate to realize informationization, digitlization, automation, interactive basic electrical network feature, promote the construction of information intelligent platform and the paces of quickening ICT (information and communication technology), cable manufacturing enterprise set about as us from electrical network " circuit " transmission of electricity link, for supporting intelligent grid provides " material guarantee ", it is extremely urgent to develop a kind of high-efficiency energy-saving environmental-protection fireproof flexible soft cable used for intelligent electric network.Simultaneously, my this new product of company's development can also be in the extensive use of industrial aspect such as oil, chemical industry, metallurgy, electric power railway, mine, municipal works.
Common cable only is made up of conductor, inserts, external sheath layer, and it does not possess anti-electromagnetism and antistatic interference capability, does not also possess resistant to elevated temperatures ability.
Summary of the invention
The present invention does not possess anti-electromagnetism, antistatic and resistant to elevated temperatures ability in order to solve common cable, the invention provides a kind of high-efficiency energy-saving environmental-protection fireproof flexible soft cable used for intelligent electric network.
The present invention includes the insulation cable core, described insulation cable core comprises power cable core, control cable core and shielded signal cable core, outside described insulation cable core, set gradually high flame retardant glass fibre belt lapping layer, copper strips lapped shielding layer, double-deck copper wire woven shield, shielding lapping layer, ceramic chemoprevention fire silicone rubber jacket layer from inside to outside, in the space between described insulation cable core and high flame retardant glass fibre belt lapping layer inserts is set, different in nature Halogen is set between power cable and control cable fills skeleton.
The present invention is rational in infrastructure, manufacture easily, serviceability is good, has less insulation dielectric loss, copper strips lapped shielding layer, double-deck copper wire woven shield, shielding lapping layer, the composite shielding mode of multi-level optimization has anti-strong electromagnetic and anti-strong electrostatic interference, and high flame retardant glass fibre belt lapping layer, ceramic chemoprevention fire silicone rubber jacket layer make this cable have fire resistant performance efficiently.Pottery chemoprevention fire silicon rubber possesses the silicone rubber for cable characteristic at normal temperatures, nonpoisonous and tasteless, environmental protection, high-low temperature resistant, anti-ozone aging, weather-resistant, superior characteristic such as electrical insulation capability is good, travelling performance is strong, good bending property, anti-bending radius are little; Under 500 ℃ of high temperature even the flame ablation more than 700 ℃; the potteryization fire-resistant silicon rubber forms hard pottery armour body protective layer; thereby play oxygen barrier and reach the fireproof effect; electric power, the unimpeded purpose of communication under fire condition, have been guaranteed; this cable can satisfy strong intelligent grid provides material guarantee for transmission of electricity requirement; and LSZH; the circuit that can be widely used in industrial aspect variable-frequency control techniques such as oil, chemical industry, metallurgy, electric power, railway, mine, municipal works is installed connection, and the excellent popularization using value is arranged.
Insulation cable core of the present invention is made up of oxygen-free copper conductor and ceramic chemoprevention fire silicone rubber insulation layer, and described ceramic chemoprevention fire silicone rubber insulation layer is wrapped in outside the described oxygen-free copper conductor.
Conductor of the present invention is that purity reaches the high-quality copper free wire twisted bundles more than 99.99%, extrudes ceramic chemoprevention fire silicone rubber insulation layer on the oxygen-free copper conductor, and this set has the effect of insulation fireproof.
Power cable core of the present invention is three groups, and described control cable core is three groups, and described shielded signal cable core is six groups.
Three power cable cores of the cable core of the stranded stranding of the present invention and three even 3+3 formulas at interval of control cable core are symmetrical arranged, the special special-shaped Halogen inserts of middle placement, many group signal control lines are placed in the outside, and twisting pitch equates that the power line core diameter is greater than the control line core diameter.The 3+3 cable core project organization of symmetry, equidistantly stranded, thus have lower effective capacitance, than low transmission impedance, energy-efficient, good electromagnetic compatibility can be provided; Place special special-shaped Halogen inserts in the middle of the cable core, fixed insulated wire cores, guaranteed cable core stability in crooked environment uses, increased compact overall structure, the rounding of cable, improved cable useful life, use safer.
