Abstract
Disclosed is an insulating direct current cable of high insulating cross linking ethylene-propylene rubber, which belongs to the cable technical field. The insulating direct current cable mainly comprises an outer sheath, a conductor is placed in the outer sheath, and an ethylene-propylene rubber insulating layer is coated outside the conductor. The insulating direct current cable employs silicone hydride cross linking ethylene-propylene rubber as an insulating layer, and employs that the ethylene-propylene rubber doesn't exist problems of space charge effect under direct current electric fields, thereby maintaining fine insulating property and obtaining a direct current cable with fine insulating property.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of isolated dc cable that adopts ethylene-propylene rubber.
Background technology
Used crosslinked polyethylene exists the space charge effect problem in the cable under DC electric field at present, and insulation property are subjected to certain restriction.Ethylene-propylene rubber (EPR) compliance is good, high resilience, and have good electrical properties, be a kind of good insulation performance material.Compare with crosslinked polyethylene, ethylene-propylene rubber exists, and remains the good insulation performance performance, and ethylene-propylene rubber itself has soft characteristic again, and therefore, ethylene-propylene rubber has irreplaceable status in the direct current power field of cables.Silane coupling ethylene propylene rubber is to make crosslinking agent with silane to carry out crosslinked new material, and the processing technology of silane coupling ethylene propylene rubber is simple, control easily, and the automaticity height, with short production cycle, quality of item guarantees easily.
Summary of the invention
The purpose of this utility model is that a kind of employing ethylene-propylene rubber will be provided, and makes full use of there are not the characteristics of space charge effect in ethylene-propylene rubber under DC electric field high-insulativity coupling ethylene propylene rubber isolated dc cable.
The purpose of this utility model is achieved in that a kind of high-insulativity coupling ethylene propylene rubber isolated dc cable, comprises oversheath 7, and conductor 1 places in the oversheath 7, and conductor 1 is coated with silane coupling ethylene propylene rubber insulating barrier 2.Conductor 1 more than two is outer by band 4 coatings.Be provided with band 4 outside the conductor 1, be provided with packed layer 3 between silane coupling ethylene propylene rubber insulating barrier 2 and the band 4.Be provided with inner covering 5 outside the band 4, be provided with armour 6 between inner covering 5 and the oversheath 7.
High-insulativity coupling ethylene propylene rubber isolated dc cable provided by the utility model, adopt silane coupling ethylene propylene rubber to make insulating barrier, utilize silane coupling ethylene propylene rubber under DC electric field, not have the space charge effect problem, remain the characteristics of good insulation performance performance, obtain the good direct current cables of insulation property.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done a step explanation.
Fig. 1 is a structural representation of the present utility model.
Fig. 2-the 4th, the utility model embodiment schematic diagram.
Embodiment
Employed silane coupling ethylene propylene rubber is to adopt ethylene-propylene rubber and liquid silane and auxiliary agent by after extruding the agent mixing, through molten hybrid junction branch moulding, the crosslinked insulated product that obtains in the utility model.By weight percentage, ethylene-propylene rubber is 97-99%, and liquid silane and auxiliary agent are 1-3%.
The utility model adopts following structure: as Fig. 1, a kind of high-insulativity cross linked insulation direct current cables comprises oversheath 7, and conductor 1 places in the oversheath 7, outside the conductor 1.
As Fig. 2, employing be single conductor 1, conductor 1 is outer be silane coupling ethylene propylene rubber insulating barrier 2, silane coupling ethylene propylene rubber insulating barrier 2 outer inner coverings 5, inner covering 5 is a cable armouring 6 outward, outermost layer is an oversheath 7.
As Fig. 3, employing be many conductors 1, inclusion 1 is coated with silane coupling ethylene propylene rubber insulating barrier 2, is filled by packed layer 3 between silane coupling ethylene propylene rubber insulating barrier 2 and the band 4, band 4 is outer to be oversheath 7.
As Fig. 4, employing be many conductors 1, inclusion 1 is coated with silane coupling ethylene propylene rubber insulating barrier 2, fill by packed layer 3 between silane coupling ethylene propylene rubber insulating barrier 2 and the band 4, outside the band 4 is inner covering 5, is cable armouring 6 outside the inner covering 5, is sheath 7 outside the cable armouring 6.
