Abstract
The invention is a hollow cable, especially can be applied to power frequency large current transmission, the electricity carrying is large, the rise of the temperature is low, and the mechanical intensity if high, and it can upgrade the security coefficient.
Description
Patent hollow core cable of the present invention is specially adapted to the big electric current of power frequency and carries, and the live flow is big, and temperature rise is low, and the mechanical strength height improves operating safety factor.
The cable of existing conveying power current in service, 1, electric conductor is solid conductor, radiating condition is poor, and collection skin coefficient is big, and AC resistance is big, temperature rise, the live flow is little, and loss is big; 2, temperature rise destroys insulating barrier easily, reduces insulating coefficient, is easy to generate phase fault and ground short circuit.3, cable cover(ing) protective layer weakness is subjected to extraneous damage easily, is easy to generate phase fault and ground short circuit, and coefficient of safety is low.
For overcoming the defective of existing cable, patent of the present invention provides a kind of hollow core cable, and the electric conductor of this cable adopts hollow electric conductor, and the main protective layer of cable is the nonmagnetic metal pipe.The characteristics of hollow core cable: 1, hollow electric conductor is when carrying power current, and skin effect coefficient is low, kf≤1, and AC resistance is little, and power loss is little, because electric conductor is hollow, forms the air heat dissipation channel naturally, and radiating condition is good, and temperature rise is low, and the live flow is big.Temperature rise is low, does not influence insulation property.Guarantee the useful life of hollow core cable.2, nonmagnetic metal pipe mechanical strength height, the protection cable performance is good, improves the cable security coefficient.3, the nonmagnetic metal pipe plays the electric shield effect, and electric shield has: a. makes Electric Field Distribution even; B. CONTROLLED POTENTIAL and the restriction electric field; C. avoid producing partial discharge at insulating surface; D. conduct Leakage Current and charging current; E. the touch voltage of danger such as is protected at characteristic.
Patent of the present invention solves the technical scheme that its technical problem adopts: electric conductor adopts hollow electric conductor, according to the electric pressure needs, on hollow electric conductor, install insulating barrier additional, on insulating barrier, install the nonmagnetic metal pipe additional, install the plastic insulation sheath on the nonmagnetic metal pipe additional, this just forms hollow core cable.
The beneficial effect of patent of the present invention is, adopts hollow core cable, and the hollow core cable skin effect coefficient is low, and power loss is little, and temperature rise is low, and current density is big, and the live flow is big, saves electric conducting material, and the mechanical strength height improves coefficient of safety.
Below in conjunction with drawings and Examples patent of the present invention is further specified.
Fig. 1 is the structural representation of patent of the present invention.
Fig. 2 is the structural representation of patent of the present invention
1. hollow electric conductors among the figure, 2. insulating barrier, 3. nonmagnetic metal pipe, 4. insulating sleeve.
Claims (4)
1, a kind of hollow core cable, its technical characterictic are that electric conductor adopts hollow electric conductor.
2, hollow core cable according to claim 1 is characterized in that hollow electric conductor installs insulating barrier additional.
3, hollow core cable according to claim 2 is characterized in that installing additional the nonmagnetic metal pipe outside insulating barrier.
