Neon Sign Tubes
Construction :
In the form of tube even upto 9 metre length and can be bend in manufacturing process to any shape/shapes.
In the form of tube even upto 9 metre length and can be bend in manufacturing process to any shape/shapes.
- It is a glass tubing consisting of two electrodes normally cylindrical in shape, of iron, steel or copper.
- It contains neon.
- Different colours are obtained by varying composition of glass and adding different substances to neon gas different colours such as orange, yellow, red, green etc. are obtained.
- Diameters of tubing - 10, 15, 20, 30 mm
- Carrying currents - 25, 35, 60, 150 mAmp respectively
- Operation voltage - 300 to 1000 volts/m of tube length
- Starting voltage 1.5 times the applied voltage.
- Voltage source - step up transformer of high reactance to get dropping characteristics.
- Operating voltage 6000 volts.
- Supporting structure - mounted on wooden frame or on metallic base. Matched with step - up transformer by connecting suitable tappings for the rated current.
- Connections between letters - made by nickel wires and glass tubings being slipped over them.
- Power factor - very low, but improved by condensers to be connected on LV side of transformer.
- If installed in open – Frequent cleaning is required say 4 times in a year.
- Keep the key of open lock systems with operator while work is being done for safety.
- Advertising.
- For signs.
- Decorative treatment of buildings.
