Types of lights

The types of standard lamp used in the park are:
- The light filament [filament lamp]
- Wap mercury lamp [high pressure mercury lamp]
- Lighting wap sodium [Sodium Vapour Lamp]
HID lamp configuration
Other than the lights mentioned above, other types may be used depending on the user's query.
Lamp connection circuits
- Filament lamp circuits
- Wap mercury lamp circuits
- Sodium lamp circuits
Place of use Filament lamp
- The road outside the airport area
Wap mercury lamp
- Roads in the area of airport
Wap sodium lamps
- Road in the central city
- As the lights are standard around the area of intersection-intersection, circle and bend roads.
Use / function lamp equipment
Choke / ballast
- The function is to elevate voltan choke at the beginning and subtracting the current flowing.
Ballast for 400w SON-(T) Lamps Ballasts for 125W Mercury Lamps
- Functions the same as choke
High presure sodium lamp Mercury vapor lamp ignitor ignitor
- The function of capacitors to correct back angkadar power [power factor] and subtracting the telecommunication wave interference.
Lighting capacitor
Using string or fius fius HRC.
Kadaran fius used depends on the load, usually between 5A and 15A sake only.
Fius function is to protect the lamp circuits and the material rather than having kerosakan if applicable circuits and load shortcuts past.
HRC fuse / base / carrier Rewireable fuse
Suis period
- Escort the electric current in a automatic instead of Streamer phase to the street lamp.
- Closing or opening suis and sesentuh [Contactor] are automatically follow the specified period. For example the light will light up at 7 pm and terpada at 7 am.
Time switches

- Escort the electric current in a automatic instead of Streamer phase to the street lamp.
- Closing or opening suis and sesentuh are automatically follow persekitaran circumstances. Lights will turn on when persekitaran become dark and terpadam when persekitran be light.
Photocell [light-dark sensor]
Penyentuh [Contactor]

- To exchange phase Streamer bekalan to street lights to escort suis period or photocell.
- To increase the number of use of light [of high electric power] in the street light system, content of the current-carrying penyentuh suis is higher than the lamp.
Pepasangan streetlight
Pepasangan expert
Pepasangan street lights made the masts on top voltan talian low. Lights mounted on the frame lights and all such materials fius, choke, alatubah, capacitors and neutral connector placed inside the coffin.
Pepasangan not good at Street lights that are made along the pole and save a typical talian underground cable system. All materials and connection cable needs to be placed on the portion of the lamp in the base of the mast or pole adjacent typical chest.

- Swap or repair equipment and do not berfugsi rosak.
- Fix the impressions of rust on the pole or crate.
- Check all cable connections.
- Make sure the metal portion has been earthed properly.
- The revision period for the 'timer switches'.
Streetlight circuits escort
The main convoy circuits are normally located within or on the chest pencawang pembekal.

Fixed - MCCB 150AF and above with ELR
