Q: What transformer can be used in a safety voltage lighting transformer?: 220V/36V or 24V isolation transformer. Double winding, high and low voltage coils, not connected.

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?: But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""

Q: Why is the two side of the lighting transformer grounded?: Neutral grounding of three-phase transformer is called working earthing: the main function is to strengthen the stability of low-voltage system potential, and to reduce the risk of overvoltage caused by grounding, high voltage, short circuit, etc..

Q: The transformer zero line has broken, has the result to the household illumination circuit?: The zero line is connected to the transformer neutral point of transformer, three FireWire for its voltage is 220 volts, according to regulations, the total can not take the zero line fuse, switch, because once the zero line is disconnected, the rest of the line will no longer be a neutral line, into the use of electrical appliances connected to two the conductor, according to the characteristics of series circuit, each phase with electrical voltage, on load distribution, change the original load smaller which phase by using electrical appliances, will damage due to excessive voltage.

Q: How many A leakage protection switches are used in 5000VA lighting transformers?: Secondary current =5000VA/220=22A, you can select the 32A leakage protection switch.

Q: Power and lighting transformers, lighting quality will be affected much?: Corresponding to the transformer power supply, in order to save costs and reduce costs, the choice of AC ignition method is better. Pure resistive load, the power factor is 1. The 3 *100W=300W is the capacity of the required transformer

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.

Q: Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design: Because of the brightness of the 36V safety voltage lamp brightness in the overhaul work is not enough, so now the well lighting design should not be 36V, and replaced by 220V, and only need to add a leakage protector on it.

Q: How to calculate the rated capacity of small transformers for lighting purposes?: But in fact, consider the total load, the importance, the location of the machine, and the future additional plan, according to the following order.

We strive to be creative and responsive to our customers' needs, which in turn help strengthen our competitive advantage in the global marketplace. We never stop pushing ourselves to be more professional and excellent.
