Description
Technical field
The utility model relates to a kind of frequency-conversion power cable, specifically a kind of soft fire resistant frequency-conversion power cable belongs to
Technical field of cable.
Background technique
With engineering project variable-frequency motor becoming increasingly popular in all parts of the world, matched frequency-changing cable demand is also increasingly
Increase, the type cable is generally the conventional inverter power cable of each producer's design, and generally 3+3 cored structure band always shields knot
Structure can be very good to prevent electromagnetic interference, and shield effectiveness is good.
Frequency-changing cable in the market is irregular, and performance indicator is different, and a part therein has fire resistant requirements.For
There is the frequency-changing cable of fire resistant requirements, product fire resistance rating in the market is relatively low, generally only meets national standard fire resistant requirements, i.e.,
IEC 60331-11/IEC 60331-21 fire resistant requirements (750 DEG C), if Authorization Notice No. is frequency conversion disclosed in CN102610317B
Cable, is cable core among the cable, and cable core includes three major insulation cores and three zero curve cores, among cable core or major insulation
It is equipped with light unit at the gap of core and zero curve core, metal screen layer, the plastic-aluminum combined layer of longitudinal wrap, isolation are set gradually outside cable core
Set, armor and oversheath, the cable enhance the function of conventional inverter cable, make it have alarm, temperature measurement, state prison
The functions such as survey, frequency feedback, signal transmission, but fire resistance rating is relatively low.
Currently, meet in the market more high target requirement Australia mark fire resisting (1050 DEG C of temperature grade) product almost without.
By cable design at soft type convenient for laying, while the cable design for meeting Australia's mark fire resisting and soft type is even more to be difficult to realize.
Utility model content
The purpose of the utility model is to provide a kind of soft fire resistant frequency-conversion power cable, it is resistance to which meets Australia's mark
Fire and soft requirement.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of soft fire resistant frequency-conversion power cable, including cable core, the cable core include three master cores and three ground wires
Core, the master core are arranged together, and the wire core is arranged between master core, and the first packet is disposed with outside the cable core
Belt, braiding layer, restrictive coating, first belting layer put up wrapped form using high fire-retardance band；The master core includes five
Class conductor, the five classes conductor are surrounded with mica tape outside, are insulating layer outside the mica tape.
The overlap rate of the Mica tape is 50%, which ensures that fire resistance (want by AS/NZS3013 fire resisting
Ask), preferably, the mica tape is two layers.
In order to further increase fire resistance, the second belting layer is provided between the braiding layer and restrictive coating, it is described
Second belting layer puts up wrapped form using high fire-retardance band.
In order to make construction of cable rounding, the extrusion packing of supporting role is provided between the master core.
It is resistance to can to meet Australia mark AS/NZS 3013 for the cable of the utility model wrapped mica tape haveing excellent performance outside conductor
Fire requires (1050 DEG C), while by conductor design at five class conductors, and liner layer structure is designed and is changed to use by extruding type
High fire-retardance band is put up wrapped, and overall construction design is more soft, is convenient for actual installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, a kind of soft fire resistant frequency-conversion power cable, be followed successively by from inside to outside cable core, the first belting layer 5,
Braiding layer 6, the second belting layer 7, restrictive coating 8.
The cable core includes that three master cores and three wire cores, the master core are arranged together, and the wire core is set
It sets between master core.In order to make construction of cable rounding, the extrusion packing 4 of supporting role is provided between the master core.
The master core includes five class conductors 1, and mica tape 2 is surrounded with outside the five classes conductor 1, is insulating layer 3 outside the mica tape 2.
The mica tape 2 is two layers, and the wrapped overlap rate of every stratus master tape 2 is 50%, which ensures fire resistance (AS/NZS
3013 fire resistant requirements).The structure of wire core uses structure in the prior art.
First belting layer 5, the second belting layer 7 put up wrapped form using high fire-retardance band.High fire-retardance band can be with
Using the oxygen barrier glass cloth band of a kind of halogen-free low-smoke high-flame fire insulation disclosed in Publication No. CN207367661U, can also use
The fire-retardant twining package tape of wire and cable of Suzhou Tai Fang cable material Co., Ltd sale.
Braiding layer 6, restrictive coating 8 structure and material be all made of scheme in the prior art.
Above-described embodiment does not limit the utility model in any way, all by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the protection scope of the utility model.
