Cable manufacturers for you to analyze the communication cable

Communication cable consists of a number of mutually insulated wires or conductors to form the core of the cable, the external has a sealed sheath of the communication line. Some are also equipped with an outer jacket outside the sheath. There are a variety of laying methods such as overhead, direct burial, pipeline and underwater. According to the structure is divided into symmetrical, coaxial and integrated cable; according to the function is divided into field and permanent cable (underground, submarine cable). Communication cable transmission band is wider, communication capacity is larger, subject to external interference is small, but not easy to overhaul. Can transmit telephone, telegraph, data and images, etc.. The following small to give you a detailed introduction to the common models of communication cables, product features and application scope and other related knowledge. First, the common type and meaning of communication cable: HYA: copper core solid polyolefin insulation moisture barrier polyethylene sheath city communication cable HYAT: copper core solid polyolefin insulation filled moisture barrier polyethylene sheath city communication cable HYAC: copper core solid polyolefin insulation self-supporting moisture barrier polyethylene sheath city communication cable HYA53: copper core solid polyolefin insulation moisture barrier polyethylene sheath steel-plastic band Armored Polyethylene Sheathed Communication Cable HYAT53: Copper Core Solid Polyolefin Insulated Filled Moisture Barrier Polyethylene Sheathed Steel Plastic Belt Armored Polyethylene Sheathed Municipal Communication Cable HYA22: Copper Core Solid Polyolefin Insulated Moisture Barrier Polyethylene Sheathed Steel Belt Armored Polyvinyl Chloride Sheathed Municipal Communication Cable HYA23: Copper Core Solid Polyolefin Insulated Moisture Barrier Polyethylene Sheathed Steel Belt Armored Polyvinyl Chloride Sheathed Municipal Communication cable HYAT22: copper core solid polyolefin insulation filled with moisture barrier polyethylene sheath steel belt armored polyvinyl chloride sheath municipal communication cable HYAT23: copper core solid polyolefin insulation filled with moisture barrier polyethylene sheath steel belt armored polyvinyl chloride sheath municipal communication cable Second, the product characteristics of the communication cable: HYA type of municipal communication cable adopts the full chromatographic insulation, aluminum-plastic composite sheath (i.e., the cable's longitudinal wrapped shielding aluminum belt and sheath). Longitudinal package shielding aluminum tape and sheath bonded into one, forming a sealed sheath), with superior electrical performance, construction convenience. Third, the application of communication cables: mainly used for the transmission of audio, 150kHZ and the following analog signals and 2048kbit/s and the following digital signals. Under certain conditions, it can also be used to transmit digital signals above 2048kbit/s. Applicable to the city, suburbs and local areas of the overhead or pipe laying lines, can also be directly buried. The above is a small organization for you to organize the wire and cable related knowledge, I hope to help you!
