The general practice is to use flat steel in the bridge through the long ground. Reason: According to the requirements of the specification, the bridge is not less than two points and the ground connection reliable connection, in order to ensure the reliability of grounding, the conventional practice is to lay a long flat steel in the bridge. This requirement is regardless of the ordinary bridge or fire distribution with the fire bridge, are required to do. Supplementary reference: For example, "Code for construction and acceptance of grounding installations for electrical installations" GB-2006 Section 3.4.6: Laying of copper wires along the cable tray, galvanized flat steel and the use of metal structures along the bridge, such as When installing the metal components for the bracket as the grounding line, the cable bridge shall be grounded in accordance with the following provisions: 1 When the total length of the cable bridge is not more than 30m, it shall not be less than 2 connected with the grounding trunk. When the total length is more than 30m, Every 20m ~ 30m increase with the grounding point of the connection point; 3 cable bridge starting and end ends should be connected with the grounding network.

Q:Will the power cord wiring with what is called, how the insulation effect

. called the cable terminal, there is heat shrinkage, put it on, and then a baking guns, it is tightened wrapped in the wiring head. Can be waterproof, the best insulation effect. . the cable terminal set of waterproof, stress control, shielding, insulation in one, with good electrical performance and mechanical properties, in a variety of harsh environmental conditions for long-term use. With the advantages of light weight, easy installation and so on. Cable terminal is widely used in electric power, petrochemical, metallurgy, railway ports and construction and other fields. . casing, usually used in the construction of the basement, used to protect the pipeline or to facilitate the installation of iron pipe. Casing classification: rigid casing, flexible waterproof casing, steel pipe casing and metal casing and so on.

Single-core cable line grounding line commonly used grounding 1. shield one end directly grounded, the other end through the protective layer to protect the ground: When the line length of 500 --- 700m and below, the shield can be used directly to one end of the ground (cable terminal Position ground), the other end through the protective cover to ground. 2. shield the midpoint of the ground: When the line length of 1000 ---- 1400m, the use of midpoint grounding. in the middle of the line position, the shield directly grounded, the cable ends of the shield through the protective cover to ground. The middle ground is usually required to install a straight connector. Install an insulated connector at the midpoint of the line. The insulated connector disconnects the cable shield, and the shield is grounded through the protective cover, and the two cables are shielded and grounded directly. 3. Shielded cross-connect cable lines are very long (1000 --- 1400m above), you can use shield cross-connect. This method is divided into three equal parts of the length of the three or three times the number of segments, each section between the installation of insulation joints, insulation joints between the three-phase shield with a coaxial cable, cross-linked box for transposition, cross The interconnection box is provided with a set of protective protector, and the two sets of insulated connectors are arranged on the line.
