Conventionally, wiring insulators were installed on ceilings and walls in order to wire electric wires in factories, warehouses, basements, parking lots, etc., but the wires were fixed when wiring cables. As the electric wiring is installed by tying and fixing the electric wires, the electric wires are tangled in a disorderly manner in the pipe or the rope. There was a problem that the handling and management of electric wires were difficult.

In general, many cables, such as power lines and communication lines, are installed in buildings, large apartment complexes, or factories in urban areas. Such cables are usually wired along underground ceilings or ceilings or walls of buildings. At this time, the cable is not only drastically droops down due to its own load, but also interferes with other structures, causing high damage, and hurting aesthetics.

Accordingly, the cable is generally supported by using a metal tray having appropriate structural strength. The tray has a substantially ladder-like configuration connected at regular intervals by a plurality of rungs for binding cables to the lower ends of two side beams arranged in parallel to each other. It is supported horizontally on the wall or ceiling by a hanger.

In order to prevent the cable from being damaged by falling foreign matter or rainwater from above, the cable is covered with an upper opening of the tray to protect the cable.

On the other hand, power lines and communication lines are simultaneously supported on one cable tray or vertically depending on the characteristics of modern complex urban structures and buildings in which quantitatively increasing telecommunication lines, ultra-high-voltage distribution lines, and alternating current electric railway lines are in a narrow area. There is no choice but to wire adjacent to the left and right, in this case, abnormal voltages and currents are induced by the power line flowing strong current to the communication line through which weak current flows, and various disturbances such as noise or crosstalk are generated in the communication facility. Disability.

These induced obstacles cause malfunctions not only in communication facilities but also in computers, electrical and electronic devices, and in severe cases, insulation breakdown, and are also caused by harmonics emitted from AC voltages of adjacent electric railways. In particular, in recent years, the use of an ultra-high voltage three-phase four-wire Y wiring system for the transmission line has become more severe inductive interference of the communication line.

The causes of induction disorders are electrostatic induction and self inductance. Electrostatic induction is a phenomenon in which charge appears on the surface of a conductor or dielectric due to the effect of the electrostatic field created by the charge when the charge is approached to a conductor or dielectric. It is caused by a high induced voltage that does not change in time as the main cause, but it is almost shielded (approximately 90%) when the grounded conductor is covered with metal as a conductor or when there is a grounded conductor near the communication line, and the distance from the power line is weak. If it is 50m or more, it is hardly affected.

On the other hand, electromagnetic induction is a phenomenon caused by the change of electric current and the magnetic flux through the circuit of one's own, and the electromagnetic induction disturbance caused by this is due to It is caused by induced voltage but also occurs in cable or underground cable with shielded coating layer, and it is also severely changed when the distance from the power line is more than 50m.

Therefore, measures to prevent induction obstacles should mainly be aimed at electromagnetic induction. For this purpose, for example, the route of the communication line is changed to reduce the access and the equilibrium length, or the cable is grounded or the metal sheathed shielded cable. Various measures can be taken.

However, it is virtually impossible to change the route of the communication line to avoid the power line in a dense urban structure, and even a shielded cable cannot effectively suppress the electromagnetic induction even if it is a shielded cable.

Moreover, since most communication cables do not have shielding metal coatings, the induced interference is so severe that not only the communication quality is greatly degraded, but also crosstalk is frequently occurring.

Accordingly, the tray supporting the power line and / or the cable is made of iron, and both ends thereof are grounded so that the induced voltage and current induced from the adjacent power line to the communication line are absorbed by the tray to suppress the induction disturbance of the communication line.

In particular, the power line and the communication line which are wired together in the interior of the building and the underground cavity are very close together, and in some cases, both wires are simultaneously connected to one tray, so it cannot overcome the induction obstacle of the communication line due to electromagnetic induction.
