What aspects should be paid attention to when installing unsightly lights and courtyard lights
View unsightly lights and courtyard lights are common lights at the moment, but many people are not very familiar with the installation requirements of courtyard lights and unsightly lights, so they don't know what to pay attention to in the later maintenance. , The editor of Xi’an Solar Street Light Dinghao Lighting is here to explain the professional knowledge for the master.
The basic requirements for the laying of buried cable lines are as follows
1. Cables, intermediate joints, and terminal heads in cable trenches, hand-hole wells, and into control boxes and power distribution cabinets should be equipped with cable indication plates that record cable specifications, models, circuit names or circuit numbers.
2. The middle or terminal end of the cable connection must be sealed and waterproof. Cutting the cable shall not damage the insulation sheath of the cable core. Each cable line construction should have the original construction record, which includes: cable model, specification, length, installation date, number of intermediate joints and terminal heads. This can prevent the conversion and modification of the cable line. Jiangsu Naite Lighting Electric Co., Ltd. is a manufacturer engaged in the production and design of solar street lamps and high-pole lamps. It has 20 years of solar street lamp production experience and builds the most professional solar street lamp manufacturer. Contact number: 13805257308 . , Facilitate the repair of buried cable lines.
3. Every time the courtyard lamp geography and cable line is changed, the corresponding technical data and cable indicator should be corrected in time to ensure the correctness of the line data.
4. Before and after cable laying, a 500V insulation resistance meter must be used to measure the insulation resistance, generally not less than 10MCl.
5. The cable core wires should be connected with round sleeves. The copper core cable is crimped with a copper sleeve. The copper sleeve is made of a copper tube containing more than 99.9% copper. The wall thickness is not less than 1mm and the length is 8-10 times the diameter of the sleeve.
6. Hand-hole wells or mark piles must be set at the joints and corners of buried cable lines. To facilitate maintenance and investigation, the spacing of hand-hole wells should be less than 50m.
Courtyard lights, outdoor unsightly lights, power cables are buried directly in the ground with a sand-covered cover in the cable trench or buried through pipes, and the pipes worn are steel pipes or plastic pipes. The plastic pipe is not strong enough to be used frequently. Laying through steel pipes has disadvantages such as heating and bending of steel pipes, on-site welding, burrs on the inner wall, complicated procedures, high costs, and easy corrosion. The use of XF7-12 buried cable sheath has the following characteristics.
1. Its flexibility and self-recoverability are very good, light texture, high strength, high temperature resistance, corrosion resistance, insulation resistance, free length, free bending, and traction steel wire is laid in the tube, which can make the construction fast.
2, XF 7-12 buried cable sheath has a service life of more than 50 years. Its price is lower than that of steel pipes of the same specification. Processes such as welding and hot bending of steel pipes can be omitted. Regardless of the method of laying, the following technical requirements must be met.
3. The physical shape is a special thread shape, and its pressure resistance and impact resistance exceed the requirements of GBlT 1338-1991.
