34 Field construction photographs - nearly five hundred building and electrical system maintenance experience, and more than seven do electrical rising mains and main switchboards were completed and replaced

Yat Full building electrical engineering performance

YAT FULL ENGINEERING was established at the beginning of 2002, initially focusing on new construction of electricity systems, school construction and government hospitals, followed by maintenance of the building of the electricity system (WR2) and water pump control system at the 200-14-05 shift camp, and has been repaired to more than five hundred buildings, including more than seventy-nine buildings, together with rising electrical mains and building and main switchboards.

Yat Full Building in Hong Kong RegionsBuilding Electrical MaintenanceThe work is well under way, as the electro-room space for each building, the main switchboard capacity, the electrical rising mains pathway and the length of the building are different, the photographs allow Owners’ Corporation, the property management company and the owner to have a full picture of the construction quality and serial arrangements of Yat.building electrical maintenance service page。

Type of building electrical engineering covered by the companion book

Yat Full Electricity Engineering case covers various parts of building public power installations - main switchboard for electrical wards, electrical rising mains to plating cables

Replacement of large rollers

The main switchboard (electrical cables, main cables) in the cable house is the general switch and protection device after the electricity company has taken power. Replacement works include the removal of old tumours, the installation of new furnaces, the refrigeration, marking and testing of the circuit and Yat Full has dealt with the replacement and repair of 1,600A and 2,500A main switchboard.Switchboard Replacement。

Electric rising mains replacement

The main dry cable, which is run by the main switchboard vertically across the various floors, involves the installation of new circuits, receptacle of sub-stations, cable collation and phase-out arrangements. The buildings above the four layers should normally be equipped with three different electrical rising mains and set up three linear sub-sections at each level.Rising Mains Replacement。

Substance cables and appliances refurbished

Sub-room cables and appliance boxes in the various floor platings are often refurbished, including the replacement of blockers, the repair of barriers, the retrospection of circuit signs, the collation of receptacles and the dismantling of waste devices, which are often unqualified projects for five years.

Electrical kitchen equipment upgraded

Two main switchboard explosions handled by Yat Full were caused by leakage of cable water, ventilation, lighting, equipment marking and impurity clean-up.building electrical maintenanceFocus.

WR2 Inspection and testing

Electricity devices are regularly checked to cover main switchboards, electrical rising mains, appliances, final electrical circuits and fixed electrical equipment, including eye inspection and power testing, and follow-up on defects.WR2 Inspections。

Maintenance of public power systems

Improvements in public corridors and gradient light circuits, lift machines and water pump supply lines, back-to-ground systems and maintenance of protection mentors, as appropriateMaintenance of the building electricityDaily scope.

Focus case: main switchboard blast repair and replacement

Bourgmestre building 1600A electric cable (2005)

In the last five years, German building caused an explosion of 1600A cables as a result of the leakage of electrical dams. Yat Full knew that the crash was carried out immediately and applied to the electricity company for a temporary electricity supply of 1200A III. The building was restored to basic electricity as soon as possible, followed by the replacement of a new 1600A ter.

Soon-and-hon-hon-hong building 2500A electric cable (2007)

Soon-hong-hong-hong-hong-hong-hong-hong building also caused an explosion of 2,500A cable due to the leakage of electrical cables over a period of two and seven years. Yat Full immediately carried out the renovation and replaced the spare parts damaged by 2,500A main switchboard and reinstated the two buildings with electricity.

Over seventy building power system renovation

In addition to emergency repair, Yat Full has completed the replacement of more than seventy buildings with electrical rising mains and building main switchboardsRenovation of the electricity systemEngineering. Such works are to recalculate the power load of the building, to design the capacity of the new old equipment, to phase out the power and to check, test and issue WR1 ' s certificate of completion after completion.

Owners’ Corporation specimens the quality of electrical engineering?

Owners’ Corporation and property management are referred to in the comparing contractor’s engineering photography, using common unconforming items listed in the five-year round-up workshop, as shown below.

Electrical appliances complete

Frequently unqualified projects of the appliance appliances are broken, and completed appliances should have complete barriers to prevent direct exposure to the band electrical component.

Signing of electrographs

Frequently unqualified projects: individual switches do not indicate the circuits to which they belong, and each switch should clearly indicate the route to which they belong, facilitate future repair and emergency isolation.

Sound refrigeration, fencing

Frequently unqualified projects: appliances of the cables are inadequate, cable cables, circuit boxes, etc., are not fitted, and the tunnels and proper receptacle are basic requirements.

Unattended electroconductors

Frequently unqualified projects: bandwidth outdoor opens, and any appliances should be protected by appropriate barriers or casings.

Protection of guides and interfaces

Frequently unqualified projects: the lithium device does not provide access to the protection of the mentors, the electroconcentrations, etc., and the new device should have a complete protection guide and equivalent receptacle.

Cleaning of cables and dismantling of discarded devices

Frequently unqualified projects: the planting of impurities in the kitchen, the discarding devices were not demolished and the devices were heavily corroborated; the electrical kitchen should be completed and the old equipment should be dismantled.

For a complete list seeFixed five-year check-ups are often not in line with standard projects。

Depende: building electrical engineering processes

The complete serial of surveying, computing, quotation, power-concession coordination, construction and testing after each completed photo back

1. On-site survey

Record the state of existing equipment, circuit pathways and space restrictions in cables, electrodes and public places.

2. Burdening

Recalculation of power system loads for building, identification of main switchboards and electrical rising mains capacity, reserved for future growth space.

3. Sub-statements

The specifications of the material, the scope of the construction and the power-free arrangements are set out in conjunction with the Owners’ Corporation ' s request for proposals and the master ' s conference procedures.

4. Coordination of suspension of electricity

In coordination with electricity companies and households, pre-screened notices and, where necessary, temporary electricity.

5. Phased construction

Removal of old equipment, installation of new equipment, emplacement of circuits and receptacles, with a view to minimizing the duration of each suspension.

6. Testing and WR1

Upon completion, a registered electrical worker was checked, tested, and a certificate of completion was issued before the circuit (WR1).
