Abstract
The utility model belongs to the technical field of a cable, in particular to an anti-interference monitoring cable. The monitoring cable comprises a radio frequency cable core, a control cable core and a power transmission cable core; and an internal sheath layer, a shielding layer, an armored layer, a flame retardant layer and an external sheath layer are wrapped outside the radio frequency cable core, the control cable core and the power transmission cable core in turn. The monitoring cable has the advantage of high flame retardant performance so that the requirement of various computers in a supercritical electricity generating system situation can be met and the safety performance among computer networks in a fire fighting system situation of a power plant can be effectively improved.
Description
Technical field
The utility model belongs to the cable technology field, specifically is a kind of jamproof monitoring cable.
Background technology
In many computer application occasions, particularly supercritical generating system field settings temperature height, voltage height, require signal accuracy height, the coefficient of safety of transmission to require high, and common cable can not satisfy its requirement, fire hazardous, cause the whole system job stability, or even the serious threat of property safety, this just needs the high flame retardant private cable.
Summary of the invention
The utility model proposes a kind of monitoring cable at the weak point that exists in the above-mentioned technology, and it is good that it has fire resistance, the characteristics that transmission signals is good.
The technical scheme that realizes the utility model purpose is as follows:
Monitoring cable, it comprises radio frequency cable core, control cable core and transmission of electricity cable core, once is enclosed with inner restrictive coating, screen, armour, flame-retardant layer and external sheath layer outside radio frequency cable core, control cable core, transmission of electricity cable core; The radio frequency cable core comprises the radio frequency conductor and is wrapped in radio frequency conductor outer radio frequency insulating barrier, radio shielding layer and radio frequency restrictive coating successively; The control cable core comprises four control cores, and every control core comprises the control conductor and be wrapped in the outer control insulating barrier of control conductor that four control cores are enclosed with stranding thin layer, control screen and control sheath outward successively; The transmission of electricity cable core comprises three transmission of electricity cores, and every transmission of electricity core comprises power transmission conductor and be wrapped in the outer transmission of electricity insulating barrier of power transmission conductor that three transmission of electricity cores are enclosed with transmission of electricity stranding thin layer, transmission of electricity screen and transmission of electricity restrictive coating outward successively; Wherein four control cores twist together, and three transmission of electricity cores twist together.
The utility model has the advantages that to have very high fire resistance, the various computers that can satisfy supercritical generating system occasion use, and can improve the security performance between power plant fire-fighting system occasion computer network effectively.
