Q: What type of low voltage transformer should be adopted for safety lighting power supply?: We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!

Q: Why should lighting transformers be used in factories and mines?: In some factories and mines (such as power plants), in order to supply power reliability, the power system is grounded in a three-phase, ungrounded, or neutral manner. In this way, the transformer must be connected to a neutral grounding type with a special transformer to supply power to the lighting.

Q: 1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires: To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.

Q: The difference between lighting transformers and control transformers: The lighting voltage is 36 and 12V, the signal lamp is 6V, the control winding is 127, 110V, the one or two insulation, and the two one is grounded.Simple lighting transformers, the two voltage is not so diverse.

Q: Is the substation separate from the power and illumination transformer?: The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.

Q: The transformer zero line has broken, has the result to the household illumination circuit?: When the zero line break line is not broken, the voltage drift of the point voltage leads to the rise of the 220V branch voltage and the reduction of the 220V branch voltage

Q: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.: So, safety regulations: lighting transformer must double winding type safety isolating transformer, prohibited the use of autotransformer.

Q: Power and lighting transformers, lighting quality will be affected much?: The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, the cold resistance of the filament and the starting factor at the same time, it is better to choose the 400VA transformer.

Q: Why can't autotransformer be used as transformer for safety lighting?: When a fault occurs, leakage of electric leakage occurs, and the original coil is transmitted to the residents at high voltage, causing disastrous effects on the human body and property!

Q: What's the function of the lighting transformer?: Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.

We not only respond to current requirements, but we also anticipate their emerging needs. We warmly welcome customers from all over the world to contact us and establish business relationships for a better future.
