I need more than the root of the dragon grams of high-ten thousand long ten thousand top 80 meters of audio and video lines, with the distributor of the VCD signal at the same time spread to a few rooms to the TV, with a network cable can replace it? If not, what line Can be replaced by more
Buried CPVC high voltage power cable sheath is a kind of CPVC, PVC as the base material, with other polymer materials to modify the special performance of the new high-voltage power cable sheathing. Mainly used for cable laying to guide and protect the cable when the role. City grid by the form of overhead lines into the underground cable form, the laying of the main row, cable trench, cable tunnel and other forms. The traditional row of pipes, and more use of steel, cement asbestos, ordinary PVC pipe. Among them, the corrosion resistance of steel pipe is poor, subject to special treatment to prevent eddy current, expensive. Asbestos pipe due to low strength in the outer concrete reinforcement, while the use of prefabricated concrete brackets, heavy weight, transport inconvenience, pipeline laying difficulties, and because of the rough wall, the joint process is not ideal, often caused by cable work well distance, Corresponding to increase the investment; another cable laying, maintenance, replacement is not very convenient, poor cable heat; asbestos tube also contains carcinogenic factors, do not meet environmental requirements. Ordinary PVC pipe strength is low, brittle, with the same as the asbestos, still need to reinforce the concrete reinforcement; thermal performance, electrical performance is poor, difficult to bear the cable overload short circuit generated when the high temperature. The use of high-voltage power cable protection tube compared with the traditional asbestos pipe, cement pipe, steel pipe, with good toughness, high strength, smooth wall friction is small, easy aging, long life, is an environmentally friendly products. Compared with the traditional excavation cable trench, it can speed up the construction speed, reduce the installation and construction costs, extend the service life of the cable.
Common fiber interface: ST.LC.SC.FCFC type fiber optic connector: external reinforcement is the use of metal sets, fastening for the screw buckle. Generally used on the ODF side (the most used on the patch panel) SC-type fiber optic connector: Connect the GBIC optical module connector, its shell is rectangular, fastening is the use of plug-pin type, no need to rotate. (The most used on the router switch) ST-type fiber optic connectors: commonly used in fiber patch panels, shell was round, fastening way for the screw buckle. (For 10Base-F connections, connectors are usually ST type. Commonly used in fiber patch panels) LC-type fiber optic connectors: connectors that connect SFP modules with easy-to-use modular jack (RJ) latches Mechanism made. (Commonly used by routers)
