Installation of medium-voltage cabinets - Underground cable installation - Low voltage cabinet installation - Low voltage cable installation Construction: - Power supply for: Crystal Martin (Viet Nam) Company Limited (Phase 3) Construction unit: Hop Thinh Electric Joint Stock Company PART I GENERAL WORK Contacts of emergency contact person and the teams’ supervisors Mr: Dao Dang Tai Position: Director Phone: 0963.058.376 Address: Hop Thinh Electric Joint Stock Company No 01, Lane 291 Le Loi Street, Hoang Van Thu Ward, Bac Giang City, Bac Giang Some work outside the construction side : 2.1 Installation of transformer - The construction area of the transformer station and installation of low and medium voltage equipment around the substation - When transforming the self-propelled crane to a capacity of 15 to 25 tons, when the transformer truck to clean around the entrance of the transformer is not trapped in the output of the crane and the lower crane Transformer From the entrance of the Crystal Martin plant to the transformer substation is the concrete road, the front area of the transformer compartment is so careful not to move the ground - During the hoisting of the transformer, attention should be paid to the crane and the substation of the transformer station and the surrounding structures, because of the large front area, so that there is enough space for the transformer hoisting work to ensure the work safe - When transformer crane pay attention to test the cable used to hook into the transformer to ensure the traction of the cable is more than three times the weight of the transformer 2.2 Installation of medium-voltage cabinets - Medium-voltage cabinet is transported to the project by truck, back to the substation, prepare the roller to move the cabinet to the position - people carrying a medium-size cabinet placed on the rollers are placed in the direction of installation When placing down the roller pay attention to the weight, when moving cabinets, use the next row to guide the cabinet to the installation position - When moving cabinets by rollers pay attention to move slowly to avoid falling cabinets roll down the house 2.3 Underground cable installation - Twisted plastic pipes are placed in the cable duct and grounded, at the corners of the pipe and the pipe connected to the end of the tube - The construction area should be located along the path from the foothold pole to the fence of the Crystal Martin factory, width 2m, the position is not enough 2m, the area enough people pass through to put the twisted plastic pipe - After finishing the twisted plastic pipe to conduct underground cable, underground cable placed at the source of the match point, using the cable to pull the cable underground When pulling to the corner of the tank to conduct each paragraph 2.4 Low voltage cabinet installation - Low voltage cabinets are sent to the works by trucks Place one of the cabinets in the position fitted with a rollers, after the six cabinets carry out the pairing of the saints and the second circuit - Low voltage cabinets are connected by bolts 2.5 Low voltage cable installation - Duplicate the cable trays Take the low voltage cable from the transformer on the cable tray and then down to the cabinet, placed on the position of the connection of the transformer head to the position of the connection and cut, pressing the two ends, made turn each thread to finish - Note that when carrying electrical cables working on high, it is necessary to have a safety belt PART II THE SAFETY MEANS Installation of transformer - When crane distortion observes the distance from the crane to the crane range, crane guidance should be provided so as not to collide and affect other structures in the crane Leave the transformer field, when crane work is completed Cranes leave the new job position to return to the next job - The fee for the transformer lifting is the entire area in front of the transformer room for prefabricated concrete of the cold house Installation of medium-voltage cabinets - When installing a medium-voltage cabinet, care should be taken not to let the cabinet fall, causing impact to the cabinet's interior - The area needed for the installation of medium-voltage cabinets is the entire area of medium and low voltage Underground cable installation - Install underground cable, pay attention to the work of underground cable, arrange the work position far apart When the digging and burial finished pulling the cable to the needle in the rope and braking not to let the rope out quickly or too slow Low voltage cabinet installation - Install the clamshell in the way of moving the cabinets so that they not fall and knock or fall over the cabinet - When linking the bars, note the phases, phases and soils in accordance with the electrical equipment regulations - The area needed for the installation of medium-voltage cabinets is the entire area of medium and low voltage Low voltage cable installation - When installing low voltage cable, pay attention to high safety PART III PREVENTIVE MEASURES Installation of transformer - Clearance of the construction site not to the construction site to nahr the process of moving crane and construction workers - Alerts where the crane crosses Installation of medium-voltage cabinets - The construction area is reserved for the construction and installation unit only, if there is another unit of the same construction, only one unit is required Underground cable installation - The construction area is reserved for the construction and installation unit only, if there is another unit of the same construction, only one unit is required Low voltage cabinet installation - The construction area is reserved for the construction and installation unit only, if there is another unit of the same construction, only one unit is required Low voltage cable installation - The construction area is reserved for the construction and installation unit only, if there is another unit of the same construction, only one unit is required ...
