Abstract
The utility model discloses a kind of screened cable; it is characterized in that; comprise conductor, insulating barrier and protective layer; described insulating barrier is set in conductor outside; arrange steel belt layer between described insulating barrier and protective layer, described steel belt layer side arranges the first screen, and described steel belt layer opposite side arranges secondary shielding layer; the first described screen is fixedly connected with insulating barrier, and described secondary shielding layer is fixedly connected with protective layer.The utility model conductor is used for the transmission of electric power or information; insulating barrier can play insulating effect; steel belt layer plays and supports inner effect; also play the effect of protection, the screen of steel belt layer both sides plays shielding action, double layer screen simultaneously; shield effectiveness is good; can prevent internal signal from disturbing, can prevent again external signal from disturbing, protective layer plays a protective role.
Description
Technical field
The utility model relates to electricity field, and in particular, the utility model relates to a kind of screened cable.
Background technology
At present; cable is made up of the conductor of one or more mutually insulated and outsourcing insulating protective layer; electric power or information are transferred to the wire at another place from one; especially the cable of transmission information, in use, due to the reason of self or external force; cable is caused to break; thus cause signal disturbing, or signal disturbing between the inner different conductor of same cable, affect the transmission of information.
Utility model content
The purpose of this utility model is to solve existing above-mentioned problem, provides a kind of screened cable.
For realizing above object; the technical solution of the utility model is a kind of screened cable; it is characterized in that; comprise conductor, insulating barrier and protective layer, described insulating barrier is set in conductor outside, arranges steel belt layer between described insulating barrier and protective layer; described steel belt layer side arranges the first screen; described steel belt layer opposite side arranges secondary shielding layer, and the first described screen is fixedly connected with insulating barrier, and described secondary shielding layer is fixedly connected with protective layer.Conductor is used for the transmission of electric power or information; insulating barrier can play insulating effect; steel belt layer plays and supports inner effect; also play the effect of protection, the screen of steel belt layer both sides plays shielding action, double layer screen simultaneously; shield effectiveness is good; can prevent internal signal from disturbing, can prevent again external signal from disturbing, protective layer plays a protective role.
As preferably, the first described screen comprises the first shielding internal layer and the first shield external layer, and the first described shielding internal layer is fixedly connected with the first shield external layer.First screen is divided into two-layer, and together, like this when one deck breaks, one deck still can play shielding action to two-side adhesive in addition.
As preferably, described secondary shielding layer comprises secondary shielding internal layer and secondary shielding is outer, and described secondary shielding internal layer is fixedly connected with secondary shielding skin.Secondary shielding layer is divided into two-layer, and together, like this when one deck breaks, one deck still can play shielding action to two-side adhesive in addition.
As preferably, arrange the first water blocking layer between the first described screen and steel belt layer, the first described water blocking layer is fixedly connected with the first screen.When first water blocking layer can prevent cable from breaking, water enters cable inside, damages the conductor in cable.
As preferably, arrange the second water blocking layer between described steel belt layer and secondary shielding layer, the second described water blocking layer is fixedly connected with secondary shielding layer.When second water blocking layer can prevent cable from breaking, water enters cable inside, damages the conductor in cable.
As preferably, described protective layer arranged outside flame-retardant layer, described flame-retardant layer is fixedly connected with protective layer.Under flame-retardant layer can prevent high temperature, cable is on fire.
The utility model has following beneficial effect: conductor is used for the transmission of electric power or information; insulating barrier can play insulating effect; steel belt layer plays and supports inner effect; also play the effect of protection, the screen of steel belt layer both sides plays shielding action, double layer screen simultaneously; shield effectiveness is good; can prevent internal signal from disturbing, can prevent again external signal from disturbing, protective layer plays a protective role.
