Abstract
The utility model discloses a DC power cable comprising a cable core. The cable core comprises an I-shaped silica gel skeleton the left side and the right side of which are respectively equipped with two wire cores arranged front and back. Each wire core comprises a conductor. The conductor and a fiber rope are twisted and then are successively wrapped in a polyimide insulating layer and a polyurethane elastomer. The cable core is successively wrapped in a calcined mica tape wrapping layer, a copper strip wrapping shielding layer, and a waterproof canvas wrapping layer, and an outer sheath. The DC power cable is reasonable in structural design and stable in quality, can be widely used in the field of rectification systems of converter stations and inversion stations and distribution system electric appliance apparatus power transmission, and has advantages of high conduction, small size, and simultaneous water and power transmission.
Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of insulation DC electric cable.
Background technology
Large-scale rectification and the contravariant equipment due to new energy field, applied are placed under complicated weather and natural environment mostly, and therefore with respect to traditional air-cooled design, a large amount of uses of water cooling equipment can make the maintenance frequency that system is compacter, stablize and reduce equipment.Aluminium tube type high voltage direct current cable not only met the requirement that water power is carried simultaneously, and the energy loss when having reduced reactor overall volume and having used.
Utility model content
The utility model object is exactly in order to make up the defect of prior art, and a kind of insulation DC electric cable is provided.
The utility model is achieved through the following technical solutions:
A kind of insulation DC electric cable, include cable core, described cable core includes I shape silica gel skeleton, left and right sides at described I shape silica gel skeleton is placed with respectively the core that place side by side two front and back, described core includes conductor, described conductor and cordage pair twist, after pair twist, in outside, be coated with successively polyimide insulative layer and polyurethane elastomer, in the outside of described cable core, be coated with successively calcining Mica tape layer, copper strips lapped shielding layer, Tarpauling lapping layer and oversheath.
The utility model has the advantages that: the utility model is coated with calcining Mica tape layer, copper strips lapped shielding layer, Tarpauling lapping layer and oversheath successively in the outside of cable core, reasonable in design, steady quality, can be widely used in commutation system, the distribution system electrical installation field of power transmission of current conversion station and Inverter Station, have advantages of that height conducts electricity, volume is little, water power is carried simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
