There is no national height limit for cables at construction sites

1. The height limit specified by the cable is different from the environment and voltage regulations, please refer to it for details.

Compare yourself. 2. Regardless of whether the height of the cable meets the requirements, whether it is listed in various places, motor vehicles entering the construction site should be obliged to care, and now the cable is responsible, but who is the owner and who is the size is different, and the amount of compensation shared is different.

Hello, according to the actual situation, check the relevant standards of the country.

Hello, how high is the national standard for cables? How high is the national standard for cables? A total of 1 national regulations refer to the provisions of Chapter VII of the Road Traffic Safety Law of the People's Republic of China, the height of the wire crossing the secondary highway shall not be less than meters, and it is clearly marked!

1.Irradiated cross-linked power cables, voltage level:; Executive Standards:

gb/。The irradiation cross-linked cable uses high-energy rays to bombard the hydrogen atoms in the poly molecular chain to discharge, so that a void is formed in the molecular chain, forming a network-like macromolecular three-dimensional structure and constituting cross-linked polyethylene; 2.Medium voltage XLPE insulated power cable, voltage level:

6/6kv-26/35kv；Executive standard: GB. The medium-voltage cross-linked polyethylene cable adopts the all-dry chemical crosslinking method, which greatly improves the mechanical performance, thermal aging performance and environmental stress capacity of the machine. 3.

High-voltage XLPE insulated power cable, voltage level: 64 110kV, executive standard: GB T 11017;127 220kV, 290 cable has excellent gas performance, dielectric loss is smaller than paper insulation and PVC insulation, and the capacitance of XLPE cable is also small; 4.

Control cable, executive standard: GB9330-88; Voltage level: 450 750V.

The product uses polyvinyl chloride or irradiated cross-linked polyethylene as the insulating layer, which has excellent electrical conductivity, mechanical properties and chemical stability, and is suitable for the control of rated voltage and below, and the protection circuit for monitoring loops and other protection occasions; 5.Computer cable, voltage level: , enterprise standard.

This product is used for shielded cables for computers, testing instruments and control systems with AC rated voltage of 300 500 and below, and is used for high anti-interference analog data transmission. Hope it helps.

Legal Analysis: Documented. The specific amount of compensation should also be checked according to the compensation standard regulations of your province and city.

Legal basis: "Land Management Law of the People's Republic of China" Article 47 Where land is expropriated, compensation shall be given in accordance with the original use of the expropriated land. The compensation fee for the expropriation of cultivated land includes land compensation fee, resettlement subsidy fee, and compensation fee for the removal of attachments and seedlings on the ground.

The land compensation fee for the expropriated cultivated land shall be 6 to 10 times the average annual output value of the cultivated land in the three years preceding the expropriation. The subsidy for the resettlement of cultivated land shall be calculated according to the number of agricultural population to be resettled. The number of agricultural population to be resettled shall be calculated by dividing the amount of cultivated land expropriated by the average amount of cultivated land occupied by the expropriated units before land requisition.

The standard of resettlement subsidy for each agricultural population to be resettled shall be four to six times the average annual output value of the cultivated land in the three years preceding the expropriation. However, the resettlement subsidy per hectare of expropriated cultivated land shall not exceed 15 times the average annual output value of the three years preceding the expropriation. The standards for land compensation and resettlement subsidies for the expropriation of other land shall be prescribed by the provinces, autonomous regions and municipalities directly under the Central Government with reference to the standards for land compensation and resettlement subsidies for the expropriation of cultivated land.

The compensation standards for attachments and seedlings on the expropriated land shall be prescribed by the provinces, autonomous regions and municipalities directly under the Central Government. To expropriate vegetable land in the suburbs of the city, the land-using unit shall pay for the development and construction of new vegetable land in accordance with the relevant provisions of the State. In accordance with the provisions of the second paragraph of this article, the payment of land compensation fees and resettlement subsidies cannot enable the peasants who need to be resettled to maintain their original living standards, and the resettlement subsidies may be increased with the approval of the people of the provinces, autonomous regions, and municipalities directly under the Central Government.

However, the sum of the land compensation fee and the resettlement subsidy shall not exceed 30 times the average annual output value of the land in the three years preceding the expropriation. According to the level of social and economic development, in the case of special royal circumstances, the standard of land compensation and resettlement subsidy for cultivated land can be raised.

Cable trays should be installed on buildings and structures (such as walls, columns, beams, floor slabs, etc.) as much as possible.

The general layout of the cable tray should be the shortest distance and meet the requirements of construction, installation and cable laying.

When the ladder frame or the perforated tray is laid horizontally, the height from the ground is not less than; The height of the trunking and non-perforated tray from the ground shall not be less than that. However, it is not allowed to be laid in a special electrical room (such as a power distribution room, an electrical shaft, and a technical floor).

The height above the ground is not less than a meter. Of course, for the safety of our lines, it is better to exceed the height as much as possible.

According to the provisions of the State Grid Corporation of China Electric Power Safety Work Regulations (Power Line Part).

Voltage level: below 10kv safety distance;

120 35kv safety distance;

63(66) 110kV safety distance;

220kV safety distance is;

330kV safety distance is;

500kV safety distance;

Notice of the State Grid Safety Supervision No. 83 on the issuance of the "State Grid Corporation of China's Electric Power Safety Work Regulations (Power Line Part, Substation and Power Plant Electrical Part) Trial Implementation".

Hope it helps, and we are now implementing this provision as well. All of the above content is hand-typed.

The safety distance of 10kV high-voltage line is 6 meters;

The safety distance of 110kV high-voltage line is 8 meters;

The safety distance of 220kv high-voltage line is 10 meters;

The safety distance along the 500kV high line is 15 meters.

Hope it helps.
