FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served

Q:For example a computer or a TV.: If it is just 110 volts, yes.

Q:An example of something would be one light flashes and another light goes off. Or Lights that are already on, turn off, another one turns on, and lights flash, then the whole process repeats itself again after a while.: A clock driven multi-pole programable time switch. They come in both mechanical and solid state flavors.

Q:For instance, could you use normal 14/2 building wire normally used in houses for 115 volt AC lights and outlets and run DC through it provided that the voltage and current does not exceed 120 volts and 15 amps?Could you use normal in-wall light switches in the same way as long as the DC volts and amps does not exceed the AC rating?: They typically need to be derated signficantly for DC. By how much depends on the device - you need to consult the relevant data sheet. To give you some idea, I have some small toggle switches here that are rated for 1A @ 125V AC but only 1A @ 30V DC. That is not at all untypical.

Q:EMP Electromagnetic Pulse: The EMP has the capacity to damage electrical equipment regardless of the source powering the electrical equipment, especially now that power generation devices depend heavily on sensitive microelectronics.

Q:How does electrical copper wires aid to temperature rise?! I don't think it is also associated with carbon emission as carbon emission mostly come from vehicles and manufacturing industry.: What you are most likely talking about is not the wire itself, but all the steps needed to make the wire. First, the mining process is typically done in large, open pit mines, which are typically several miles in diameter and several miles deep. The vehicles used to mine and transport the copper ore burn copious amounts of fossil fuels. Then you move on to the smelting process. The smelting of copper ore is not easy. The smelting process (melting and refining the ore) takes massive amounts of heat and energy. The burning and melting process releases massive amounts of pollution, especially carbon, along with other nasties, like sulfur dioxide, which is why we are having so many problems with acid rain. Since we use copper in all of our electronics, and we are a consumerist society focused on new gadgets, the wires used to make said gadgets accounts for a large percentage of global warming pollution.

Q:I need definitions of ship EquipmentMain switchboard:Distribution bus bars:Ship service generators:Main Engines:Prime mover:propulsion generators:propulsion motors:: It is assumed that this enquiry is in respect of large cargo or passenger vessels, not little pleasure boats. Main switchboard. This is the electrical switch panel to which all of the supplies from the service generators are led and from which all supplies to engineroom electrical equipment, deck machinery and the ships general electrical equipment, galley, navigation equipment, lighting, ventilation etc are supplied. The main switchboard comprises distribution bus bars, switches, meters and on AC ships, now in the the majority, the equipment required to synchronise the phases of the service generators. The distribution bus bars are the principal electrical conductors to which the generator outputs can be switched and from which the circuits to the rest of the ships electrical equipment are supplied. There are usually four bus bars, three carrying electricity at 415 or 440 volts three phase and a neutral bar. The current is usually supplied with a frequency of 50 Herz or 60 Herz. Ships service generators are in modern ships alternator units which supply all electrical requirements with the exception of the ship's propulsion. They are normally powered by diesel engines or steam turbines and in some naval vessels by gas turbines. Main engines. This term is invariably used for the vessel's propulsion machinery. Prime mover. This is a general term not restricted to marine practice for any machine the converts the energy of a fuel or the heat energy of steam into kinetic energy. Propulsion generators. These can be DC generators or AC alternators which have outputs dedicated for ship's propulsion purposes. The are usually connected independently of the main switchboard via a dedicated propulsion switchboard. Propulsion motors. These are electric motors which drive the ship's propellers. They are usually inboard but many modern cruise ships have their propulsion motors within pods which are outside of the main hull.

Q:I am an undergraduate in Electrical Engineering and I want to design and work with generators. What institutions research electrical generators? What companies design/build electrical generators? What is the difference between electric drive systems and generators? are they the same thing?Much thanks.: Design of those is pretty straightforward, as they have been around for over 100 years. So your only possibility is to find companies that manufacturer them. Small ones are usually made in China. Large ones that are used in power plants are made by companies like GE and Siemens. Contact them for information on job opportunities. electric drive systems ? do you mean electric motors?

Q:1.What is Rated AC voltage? Why we would like to state Rated instead of Nominal?2.What is Nominal AC voltage?3.Explain rms value for AC voltage. What is it's relation to Rated/Nominal Voltage?: Rated voltage could also be the maximum voltage that a type of wire, plug, socket or circuit breaker is designed for. In that case, the rated voltage may be considerably higher than the nominal voltage. Nominal voltage is the standard value that is used when referring to a voltage level. If the nominal voltage is 220 volts, the actual voltage might be 5 or 10% higher or lower. So in French, rated voltage is sometimes used for voltage nominal, but it is also translated as voltage maximum admis I hope this helps .

Q:e.g. medical equipment: Best thing to do is use a surge protector and if the equipment is costly enough use one voltage stabiliser/CVT/UPS in addition.

Q:I will be traveling to India in the next month. I have my laptop, camera and other electrical equipments which will need to be charged. I have heard that the voltage in India is 220 V and not 110 V. All my appliances work at 110 V, how do I make it work in India?: There are some things that Radio Shack is good for. Converters for foreign travel is one of them. You'll need an adapter for the different plug configuration AND you'll need a voltage converter. Both are also available as a package. And a lot cheaper, cleaner, and more reliable than trying to build your own.
