1. Insulation test: telemetering the insulation resistance between lines and to the ground with a megger to check whether the cable is in good condition and whether there is leakage. All test values should meet the specification requirements. After telemetering, the core wire should be discharged to the ground. The cable end shall be sealed with rubber blanket and then wrapped with rubber blanket.

2. Street lamp installation:

(1) The installation height (from the light source to the ground), elevation angle and installation direction of street lamps at the same location should be consistent.

(2) The longitudinal centerline of the lamp installation and the longitudinal centerline of the lamp arm shall be consistent, and the horizontal line of the lamp shall be parallel to the ground. After fastening, there shall be no deflection through visual inspection.

(3) The lamp cap shall be firmly fixed, the adjustable lamp cap shall be adjusted to the correct position according to the design, and the lamp cap wiring shall meet the requirements

(4) For fastening of various nuts, gaskets and spring washers should be added.

3. Installation of electrical equipment:

(1) After the materials arrive at the site, they can be installed and used only after they pass the unpacking inspection.

(2) The center lines of moving contacts and static contacts shall be consistent, and the contacts shall be in close contact.

(3) The switching contact of the secondary circuit auxiliary switch shall act accurately and contact reliably.

(4) Mechanical locking and electrical locking actions shall be accurate and reliable.

(5) The grounding system must be firm and reliable and meet the requirements of drawings and specifications.

4. Test and pressure test: commissioning equipment, instruments and instruments must be inspected and qualified by relevant units with measurement qualification recognized by the state, and shall be used and kept by special personnel.

(1) The insulation test of the electrical circuit must be qualified, the impedance matching is appropriate, the wiring is correct, and the signs are clear and complete.

(2) The instrument shall be sensitive, accurate in measurement, correct in zero position, and its indication accuracy, variation and recording accuracy shall meet the requirements of the manual.

(3) After installation, check and confirm that there is no error before sub item commissioning.

(4) After the commissioning of each sub item, the system commissioning, linkage commissioning and trial operation can be carried out.
