( Industry news] Control cable installation considerations dianlan P control cable is common in our life, so we learn about the control of the considerations that cable installation. 。 The eaves: cable in not only direct exposure to the sun, or more than the heat standard LAN cable can be used, it is recommended to use the pipe. Ultraviolet ( UV) 'don't leave without uv protection within the cables use in direct sunlight environment. 。 Outside the wall: avoid direct sunlight metope and man-made damage. Heat 'cable in the temperature of the metal pipe or trough is higher, a lot of polymeric material when the temperature drops, life will be shorter. 。 In the pipeline, Plastic or metal) : such as in the pipeline, should pay attention to the breakage of the plastic pipe and metal pipe of heat conduction. Mechanical damage, Repair costs) 'cable repair is very costly, need at least twice in each breakpoint termination. 。 Dangling application/aerial cable: to consider the cable sag and pressure. Intend to take what kind of binding way? If the cable is direct sunlight. 。 The underground cable conduit laid directly: this kind of environment is the control range is small. The installation of the cable trench should make the dry or wet degree of inspection on schedule. Grounding 'if the control cable shield grounding is required, then must comply with the corresponding standard. 。 Underground pipes: to facilitate future upgrades, cable replacement and away from the surface pressure and the surrounding environment, auxiliary pipe from, auxiliary pipe is a good method. But don't hope that the pipeline will stay dry, it will affect the selection of cable types. The water water 'in the local area network (LAN) twisted-pair cable will add more cable capacitance, which reduces the impedance and cause near end crosstalk problems. Understand the matters needing attention when the control cable installation, electrical installation on need not completely blind.
