	Insulated wire	Naked wire	Insulated wire	Naked wire	Naked wire	Naked wire	Naked wire
Distance	1.0 m	2,.0 m	1.5 m	3.0 m	4.0 m	6.0 m	7.0 m

- The height xoilac tv trực tiếp bóng đá hôm nay corridor is from the bottom xoilac tv trực tiếp bóng đá hôm nay pole foundation to the heighest point xoilac tv trực tiếp bóng đá hôm nay the works plus the safety distance vertically specified in the following table:

Voltage	Up to 35 kV	110 kV	220 kV	500 kV
Distance	2.0 m	3.0 m	4.0 m	6.0 m

Note:Buffer zones xoilac tv trực tiếp bóng đá hôm nay above-ground or overhead cables shall cover an area xoilac tv trực tiếp bóng đá hôm nay0.5mfrom the outermost cables to the outside.

2. Trees inside and outside buffer zones xoilac tv trực tiếp bóng đá hôm nay overhead high-voltage transmission lines

According to Article 12 xoilac tv trực tiếp bóng đá hôm nayNghị định 14/2014/NĐ-CP(amended by Points a, b and c Clause 8, Article 1 xoilac tv trực tiếp bóng đá hôm nayNghị định 51/2020/NĐ-CP) regulations on distance between trees inside and outside buffer zones xoilac tv trực tiếp bóng đá hôm nay overhead high-voltage transmission lines is as follows:

For trees inside buffer zones xoilac tv trực tiếp bóng đá hôm nay transmission lines

- For power lines with voltage up to35 kVin cities, towns and townships:

+ For conducting line with voltage up to35 kVin cities, towns…, the distance from any point xoilac tv trực tiếp bóng đá hôm nay the trees to the conducting wire in the state xoilac tv trực tiếp bóng đá hôm nay maximum deflection is not less than the distance specified in the following table:

Voltage	Up to 35 kV
Distance	Insulated wire	Naked wire
	0.7 m	1.5 m

+ For the line with voltage from110 kV to 500 kVin cities, towns…, the trees must not be higher than the lowest conducting line except for special cases, there must be technical measures to ensure the safety permitted by the People’s Committees xoilac tv trực tiếp bóng đá hôm nay provinces and centrally-run cities (provincial People’s Committees). The distance from any point xoilac tv trực tiếp bóng đá hôm nay the trees to the conducting line at the state xoilac tv trực tiếp bóng đá hôm nay maximum deflection must not be less than the distance specified in the following table:

Voltage	110 kV	220 kV	500 kV
Distance	Naked wire
	2.0 m	3.0 m	4.5 m

+ For the lines outside cities, towns…, the distance from the highest point xoilac tv trực tiếp bóng đá hôm nay the trees vertically to the height xoilac tv trực tiếp bóng đá hôm nay the lowest conducting line at the state xoilac tv trực tiếp bóng đá hôm nay maximum deflection is not less than the distance specified in the following table:

Voltage	Up to 35 kV		110 kV	220 kV	500 kV
Distance	Insulated wire	Naked wire	Naked wire
	0.7 m	2.0 m	3.0 m	4.0 m	6.0 m

+ For the overhead conducting line across special-use forest, protection forest, production forest and garden, the vertical distance from the average height xoilac tv trực tiếp bóng đá hôm nay trees maximally grown to the lowest conducting line at the state xoilac tv trực tiếp bóng đá hôm nay maximum deflection must not be less than distance specified at Point c, Clause 1 xoilac tv trực tiếp bóng đá hôm nay this Article.

For trees outside buffer zones xoilac tv trực tiếp bóng đá hôm nay transmission lines and outside cities and towns

The distance between any part xoilac tv trực tiếp bóng đá hôm nay a tree when it falls and any part xoilac tv trực tiếp bóng đá hôm nay a transmission line shall be longer than the distance specified in the following table:

Voltage	Up to 35 kV	110 and 220 kV	500 kV
Distance	0.7 m	1.0 m	2.0 m

Note:

- For trees which rapidly grow within03 monthsand possibly violate the distance specified in Clause 1 and 2 xoilac tv trực tiếp bóng đá hôm nay this Article. For the trees which have no longer economic efficiency must be fallen and not be planted again.

- Rice, crops and plants must only be planted at least 0.5 m from the pole foundation and sleeper.

3. Requirements for houses and workplaces to remain inside buffer zones xoilac tv trực tiếp bóng đá hôm nay overhead high-voltage transmission lines with a voltage xoilac tv trực tiếp bóng đá hôm nay up to 220 kV in Vietnam

According to Article 13 xoilac tv trực tiếp bóng đá hôm nayNghị định 14/2014/NĐ-CP(amended by Points a, b and c Clause 9 Article 1 xoilac tv trực tiếp bóng đá hôm nayNghị định 51/2020/NĐ-CP) stipulating requirements for houses and workplaces to remain inside buffer zones xoilac tv trực tiếp bóng đá hôm nay overhead high-voltage transmission lines with a voltage xoilac tv trực tiếp bóng đá hôm nay up to 220 kV in Vietnam:

- Houses and constructional works are permitted to exist within the safety corridor xoilac tv trực tiếp bóng đá hôm nay overhead conducting line with voltage up to 220 kV if meeting the following conditions:

+ Roof and wall must be made xoilac tv trực tiếp bóng đá hôm nay non-combustible materials.

+ There is no obstruction xoilac tv trực tiếp bóng đá hôm nay checking, maintenance and replacement xoilac tv trực tiếp bóng đá hôm nay parts xoilac tv trực tiếp bóng đá hôm nay the transmission lines.

+ The distance from any part xoilac tv trực tiếp bóng đá hôm nay houses or works to the nearest conducting line when the line is at the state xoilac tv trực tiếp bóng đá hôm nay maximum deflection is not less than the distance specified in the following table:

Voltage	Up to 35 kV	110 kV	220 kV
Distance	3.0 m	4.0 m	6.0 m

+ The electric field intensity is less than 5 kV/m at any point outside the house and one meter (01) from the ground and less than or equal to 1 kV/m at any point inside the house and one meter (01) from the ground.

Note: For houses and works within the safety corridor xoilac tv trực tiếp bóng đá hôm nay overhead conducting line with voltage xoilac tv trực tiếp bóng đá hôm nay 220 kV, besides meeting the above conditions (Article 13 xoilac tv trực tiếp bóng đá hôm nayThông tư 05/2021/TT-BCTdated September 22, 2021).

+ Minister xoilac tv trực tiếp bóng đá hôm nay Industry and Trade shall elaborate on the scope and techniques for grounding xoilac tv trực tiếp bóng đá hôm nay metal structures xoilac tv trực tiếp bóng đá hôm nay houses and structures inside and adjacent to buffer zones xoilac tv trực tiếp bóng đá hôm nay overhead 220 kV transmission lines and adjacent to buffer zones xoilac tv trực tiếp bóng đá hôm nay 500 kV transmission lines.
