Abstract
The utility model relates to a broadband local communication line, which comprises an outer jacket, characterized in that: two copper wire pair twists are arranged, a layer of inner jacket is arranged outside the two copper wire pair twists; a galvanized iron wire is arranged parallel with the two copper wire pair twists covered by the inner jacket, the galvanized iron wire and the two copper wire pair twists covered by the inner jacket are covered by the outer jacket. The diameter of the two copper wire pair twists is 0.5mm. The inner jacket is made of polyethylene. The diameter of the galvanized iron wire is 1.2mm. The outer jacket is made of polyvinyl chloride; the galvanized iron wire is covered by a layer of polyethylene. The utility model has the advantages that the highest frequency transmission can attains 30MHz and 100MHz, and can transmits data, images, characters and electrical signals. The single audio transmission of the communication lines of the copper covered steel wire telephone users, the audio local telephone and ADSL broadband function can be realized, and the communication line is simple and convenient to operate and has a long period of usage.
Description
Technical field
The utility model relates to a kind of order wire, particularly a kind of broadband intracity communication line.
Background technology
What the at present existing cable that uses when entering user side in local telephone network adopted is Copper clad Steel Wire for Telephone users, it can only use in audiorange, that is to say the only logical phone of line, and resistance is bigger, electric property is poor, and now people have been not limited to for the use of telephonic communication line and have made a phone call, and will surf the Net, need the transmission data, image, the literal and the signal of telecommunication etc., and the Copper clad Steel Wire for Telephone users of using in the present local telephone network can only be to carry out under a narrower bandwidth and low frequency condition, can't satisfy the transmission requirement in the wideband broadband in the modern communications technology, the Copper clad Steel Wire for Telephone users that therefore enters user side is a bottleneck of current telephonic communication development.
Summary of the invention
The purpose of this utility model is that what to solve that the cable that uses when entering user side in the prior art adopts is the existing the problems referred to above of Copper clad Steel Wire for Telephone users, and a kind of broadband intracity communication line is provided.The utility model design broadband intracity communication line comprises oversheath, it is characterized in that: two copper wire twisted pair wires are arranged, outside two copper wire twisted pair wires one deck inner sheath is arranged; A galvanized wire is arranged, and galvanized wire be arranged in parallel with two copper wire twisted pair wires that are enclosed with inner sheath, outside galvanized wire and two copper wire twisted pair wires that are enclosed with inner sheath oversheath is arranged.The diameter of two copper wires is 0.5mm.Inner sheath is a polyethylene.The diameter of galvanized wire is 1.2mm.Oversheath polyvinyl chloride, galvanized wire have layer of polyethylene outward.The utility model has the advantages that high-transmission frequency can reach 30MHZ and 100MHZ, can transmit data, image, literal and the signal of telecommunication etc.Can solve the single audio frequency transmission of Copper clad Steel Wire for Telephone users well, realize audio frequency local telephone network and ADSL broadband feature, this order wire is easy and simple to handle, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise oversheath 1 among the figure, it is characterized in that: two copper wire twisted pair wires 2 are arranged, outside two copper wire twisted pair wires 2, one deck inner sheath 3 is arranged; A galvanized wire 4 is arranged, and galvanized wire 4 be arranged in parallel with two copper wire twisted pair wires 2 that are enclosed with inner sheath 3, outside galvanized wire 4 and two copper wire twisted pair wires 2 that are enclosed with inner sheath 3 oversheath 1 is arranged.The diameter of two copper wire twisted pair wires 2 is 0.5mm.Inner sheath 3 is a polyethylene.The diameter of galvanized wire 4 is 1.2mm.Oversheath 1 is a polyvinyl chloride, and layer of polyethylene 5 is arranged outside the galvanized wire 4.Because having adopted diameter is that two copper wire twisted pair wires 2 of 0.5mm are as conductor, the frequency of its transmission can reach 30-100MHZ, can transmit data, image, literal and the signal of telecommunication etc., and extrude the poly inner sheath 3 of last layer on the line, can strengthen moisture resistance, also make simultaneously line loosening to Stability Analysis of Structures, can be through by bending, coiling, wind, vibration etc. keep the stable of its electric property.Add a galvanized wire 4 in the structure and make reinforcement through the φ 1.2mm of special processing, and can be at its outsourcing layer of polyethylene 5, to strengthen the antiseptic property of galvanized wire 4.Its tensile strength is similar with former copper covered steel wire.Oversheath 1 adopt pvc material neither can with the polyethylene adhesion as insulating barrier, guarantee the product pliability again, guarantee that simultaneously the product constructing operation is simple and convenient.
Claims (6)
1, intracity communication line in broadband comprises oversheath, it is characterized in that: two copper wire twisted pair wires are arranged, outside two copper wire twisted pair wires one deck inner sheath is arranged; A galvanized wire is arranged, and galvanized wire be arranged in parallel with two copper wire twisted pair wires that are enclosed with inner sheath, outside galvanized wire and two copper wire twisted pair wires that are enclosed with inner sheath oversheath is arranged.
2, by the described broadband of claim 1 intracity communication line, it is characterized in that: the diameter of two copper wires is 0.5mm.
