Abstract
The utility model relates to a polyether-ether-ketone insulating transformer early failure monitoring and communication cable, which comprises at least one conductor, wherein an extruded insulating layer is arranged outside each conductor, glass fiber fillers, a copper strip shielding layer, an inner protective sleeve, a steel strip armor layer and an outer protective layer are arranged outside the insulating layer in sequence. The polyether-ether-ketone insulating transformer early failure monitoring and communication cable has various functions of high-temperature resistance, flame retardancy, non-toxic, low capacity and anti-interference, is suitable for the transmission of analog signals and digital signals. By adopting polyether-ether-ketone insulating and a low smoke zero halogen crosslinking polyolefin protective sleeve, the long-term working temperature of the cable can reach 250 DEG C, thereby reliably and realtimely transmitting transformer oil dissolved gas hue analyzing signals and temperature signals, and providing guarantees for the safety of operations of large power transformers.
Description
Technical field
The utility model relates to a kind of technical field of electric wires and cables, relates in particular to a kind of polyether-ether-ketone insulating transformer initial failure monitoring communication cable.
Background technology
Communication cable is used for transmission of analogue signal and digital signal as communication apparatus commonly used or equipment, therefore improve capability of electromagnetic shielding, guarantee that the normal transmission of signal seems of crucial importance for communication cable, especially high-power transformer needs real-time transmission transformer oil dissolved gas hue analysis signal and temperature signal, thus on high-power transformer all supporting malfunction detection communicating cable.
The utility model content
The utility model provides a kind of high temperature resistant, fire-retardant nontoxic, jamproof polyether-ether-ketone insulating transformer initial failure monitoring communication cable in order to overcome the above problems.
The technical solution of the utility model is: comprise at least one conductor, and the every outer extruded insulation layer of conductor, insulating barrier is provided with glass fiber inserts, copper strips screen, inner sheath, steel-tape armouring layer and oversheath outward successively.
Described insulating barrier is a polyether-ether-ketone, and inner sheath and oversheath are the low smoke and zero halogen cross-linked polyolefin, and oxygen index is not less than 32.
The utlity model has multiple functions such as high temperature resistant, fire-retardant nontoxic, low Xc interference, be applicable to the transmission of analog signal and digital signal, adopt polyether-ether-ketone insulation and low smoke and zero halogen cross-linked polyolefin sheath, the long-term work temperature of cable can reach 250 ℃, real-time Transmission transformer oil dissolved gas hue analysis signal and temperature signal are given security for ensureing the high-power transformer safe operation reliably.
