Abstract
The utility model discloses a variable frequency cable for ships, comprising a conducting wire and a ground wire, as well as a copper foil strip tinned copper wire twisted drainage line overall shielding layer, a tinned copper wire woven overall shielding layer and a crosslinked polyolefine sheath, which are sequentially wrapped outside the conducting wire and the ground wire from inside to outside, wherein the conducting wire comprises a tinned twisted soft copper conductor and a crosslinked polyethylene insulating layer wrapped outside the tinned twisted soft copper conductor. By improving material and structure, the variable frequency cable for the ships is softer and easier to lay and has excellent voltage resistance and temperature resistance, good shielding performance, high efficiency, energy conservation, stability and long service life.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of frequency-changing cable.
Background technology
Electric wire is meant the material that is used for electric power, communication and associated transport purposes.Along with the continuous expansion of industry sizes such as power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.At present, more and more adopted equipment such as converter plant energy-conservation on boats and ships and the platform, reduced equipment attrition, the purpose that prolongs equipment life to pursue, and the use of frequency conversion equipment is that the demand of frequency-changing cable is increasing to supporting with it private cable, and performance requirement is also more and more higher.Frequency-changing cable makes people must take all factors into consideration when it is carried out structural design because of its special environment for use and performance requirement, optimizes and forms.With regard to structural design, mainly set about research from the influence and frequency-changing cable two aspects that influence to external world of outer bound pair frequency-changing cable, also to consider simultaneously frequency-changing cable dielectric voltage withstand, lay space, bending radius or the like.The deriving of electric wire/new product mainly be in response to occasion, application requirements is different and the convenience of equipment and reduce the requirement of equipment cost etc., and adopt new material, special material or change product structure or improve technological requirement and produce.
The utility model content
The purpose of this utility model provides a kind of material and all improved frequency-changing cable peculiar to vessel of structure, has softness and easily lays, withstand voltage, heatproof, advantages of good shielding performance, and the characteristics of long service life.
For achieving the above object, by the following technical solutions:
A kind of frequency-changing cable peculiar to vessel, comprise lead and ground wire and wrap up its outer stranded drainage thread bulk shield of Copper Foil band tinned copper wire, tinned copper wire braiding bulk shield, cross-linked polyolefin sheath from inside to outside successively, wherein, described lead comprises zinc-plated stranded soft copper conductor and wraps up its outer crosslinked polyetylene insulated layer.
Preferably, described lead is three strands.
Further, described ground wire is three strands.
The utility model adopts zinc-plated stranded soft copper conductor by to the improvement of material and structure, make the utility model more softness easily lay; The crosslinked polyetylene insulated layer that adopts has good withstand voltage and heat resistance; The bulk shield that copper strips adds the copper wire braiding structure guaranteed the good electrical magnetic shield performance of cable, thereby weakened the interference of equipment and system to external world of frequency-changing cable electromagnetic wave; Efficient energy-saving, and stable performance, long service life; In addition, the design of three strands of leads and three strands of ground wires can effectively suppress the odd harmonic in the high order harmonic component, has effectively improved the interference free performance of cable, is particularly suitable for uses such as all kinds of boats and ships, platform device.
