Abstract
A kind of HVDC Transmission system electronic module is connected with measurement head uses high Anti-interference cable, and it is redesigned to cable shield：Using line to shield components, many wrapped shieldings of strand and always three layers of shielding construction of shielding so that cable has superpower shielding properties；Adjusting and optimizing component pair twist pitch, reduces the influence of capacity unmbalance；Using low smoke, zero halogen type sheath material, it is ensured that while cable high transformation property, the characteristics of having environmental protection concurrently again；With superpower anti-interference, low-loss and stabilization signal transmission performance.
Description
Technical field
The utility model is related to HVDC Transmission（HVDC）Connection cable between system electronic module and measurement head, with anti-
The performances such as interference, low-loss, the transmission of safety and stability signal.
Background technology
HVDC Transmission（HVDC）Connection cable is needed with anti-interference between the electronic module and measurement head of system, low to damage
Consumption, and security and stability and bending property require high, it is contemplated that the requirement of the factor such as environmental protection, existing product is difficult to reach
To above-mentioned requirements.
The content of the invention
Technical problem to be solved in the utility model be for above-mentioned the deficiencies in the prior art there is provided one kind it is anti-interference,
Low-loss, and the HVDC Transmission system electronic module of security and stability and good bending property is connected with measurement head and uses Gao Kanggan
Disturb cable.
In order to solve the above technical problems, the technical scheme that the utility model is taken is：Core is soft by Equations of The Second Kind or the 5th class
The crosslinked polyetylene insulated layer composition of conductor outer cladding；Cord assembly by both threads core pair twist when with polyester belt it is wrapped after plus tin-coated copper
Silk makees drainage thread, is constituted further around one layer of foil shielding layer of bag, described drainage thread is contacted with the aluminium face of foil shielding layer；Some cores
Line component is twisted into cable core；After the wrapped sheath of cable core outer cladding polyester belt plus tinned copper wire makees the second drainage thread, then it is outer around
The second foil shielding layer is wrapped, the second drainage thread is contacted with the aluminium face of the second foil shielding layer；Extruded outside second foil shielding layer
Outer jacket is extruded outside inner sheath, the total screen layer of inner sheath outer cladding, total screen layer.
A kind of prioritization scheme of such scheme is：Described total screen layer is made to draw in the steel band of armouring provided with some copper wires
Streamline is constituted.
The present invention is redesigned to cable shield：Using line to shield components, the wrapped shielding of many strands and
Always shield three layers of shielding construction so that cable has superpower shielding properties；Adjusting and optimizing component pair twist pitch, reduces electric capacity not
The influence of balance；Using low smoke, zero halogen type sheath material, it is ensured that while cable high transformation property, the characteristics of having environmental protection concurrently again.
The beneficial effects of the utility model are：With superpower anti-interference, low-loss and stabilization signal transmission performance.

Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, core is made up of Equations of The Second Kind or the crosslinked polyetylene insulated layer 2 of the outer cladding of the 5th class flexible conductor 1；Cored wire
Component by both threads core pair twist when with polyester belt it is wrapped after plus tinned copper wire make the first drainage thread 3, further around wrapping the first aluminum foil shielded
Layer 4 is constituted, and the first described drainage thread 3 is contacted with the aluminium face of the first foil shielding layer 4；Some cord assemblies are twisted into cable core；
Tinned copper wire is added to make the second drainage thread 6, then outer wrapped second foil shielding layer after the wrapped sheath 5 of cable core outer cladding polyester belt
7, the second drainage thread 6 is contacted with the aluminium face of the second foil shielding layer 7；The outside of second foil shielding layer 7 extrudes inner sheath 8, interior shield
Cover and extruded outside the 3rd drainage thread 10 constituted in 8 outer cladding armouring tapes 9, armouring tape 9 provided with some copper wires, armouring tape 9
Outer jacket 11.
