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: If it is, why?: it is not. that is why there is test equipment that does just that (measure earth resistance). resistance is function of resistivity, area of the corsssection and length of the medium. due sheer size of the electrodes placed in ground we can achieve large contact surface. undergroud water and minerals also reduce resistance. different applications may requre that earth resistance is below some limit. if the limit is small value, grounding will be big job and cost a lot. many new buildings have metal strips placed along foundations (to get large contact surface). dry soil is less conductive and values can vary quite a bit.

Q: I have heard that an electrical ark can kill you so I would like to know what circumstances creares this condition.: *An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally nonconductive media such as air. A synonym is arc discharge. Undesired or unintended electric arcing can have detrimental effects on electric power transmission and distribution systems and electronic equipment. Devices which may cause arcing include switches, circuit breakers, relay contacts, fuses and poor cable terminations. When an inductive circuit is switched off the current cannot instantaneously jump to zero; a transient arc will be formed across the separating contacts. Switching devices susceptible to arcing are normally designed to contain and extinguish an arc, and snubber circuits can supply a path for transient currents, preventing arcing. If a circuit has enough current and voltage to sustain an arc formed outside of a switching device, the arc can cause damage to equipment such as melting of conductors, destruction of insulation, and fire. An arc flash describes an explosive electrical event that presents a hazard to people and equipment. *An arc-fault occurs when loose or corroded connections make intermittent contact and causes sparking or arcing between the connections. This translates into heat, which will break down the insulation of the wire and can be the trigger for an electrical fire. Unlike a short circuit, that is a hot wire coming into contact with a ground or neutral wire, arcing may not trip the circuit breaker. If you’ve ever heard a switch buzzing, hissing, or popping, you’ll know what I’m talking about. In order to protect your home, an arc-fault circuit interrupter can be used to detect just such a problem.

Q: For example a computer or a TV.: Only if it is not automatically switching.

Q: Hi,My friend said i need a surge protector for all my electrical equipment otherwise they could mess up?: It should already be built into the laptop. However, you don't need a $100 surge protector, computer stores have many for less than $20 (or hardware stores). Try there first, it wouldnt hurt to have extra protection.

Q: I live in a condominium made of concrete without an electrical ground wire. Is it possible for me to hammer a nail into the concrete wall and attach the ground wire onto the nail. Will this be effective? If not can anyone please suggest a method for me to be able to ground my appliances. Much thanks in advance.My country/city has almost no electrical regulation/laws and the little that we have are barely implemented and never inspected.Safe DIY Guerilla methods are accepted: Wisdumb, no, this will not work. A ground provides a substantial electrical connection to *the ground* one way or another. In the U.S, to provide a ground for a radio or T.V. antenna, a long copper-coated stake is driven into the ground, and the area around it is covered in salt to assist conductivity (water or rain dissolves the salt into the surrounding soil). A thick wire is then attached to the copper stake and then run to the antenna and mast. This may give you some ideas, but may not be fully effective for your needs. Maybe an electrician will answer. Good luck. Don't kill yourself.

Q: Hi all, i wish to travel to the states soon and would like to bring some electrical items back, as-well as clothes when i travel to New York. From research i have already learned that these goods brought back into the UK can total ?340. But my question is this, if i travel to the US with very little luggage - no clothes or electrical equipment. Then in New York i buy a nice laptop, ipod touch, digital camera (but take the electrical stuff in with my hand luggage) how will they be able to know if the items i want to bring on the plane were in fact brought with me from the UK to US and were already mine?Also if customs say that i have to pay tax for going over the ?340 - how much will it be? say e.g. on a $2000 laptop?: They might have a suspicion that you are importing items back to the UK (rather than having taken them there in the first place) when looking at the US-style electrical plugs. Given that these are not the same kind of plug as is used in the UK, you might raise suspicion when everything you bring back has US plugs (instead of UK plugs with a US adapter). I'd also note that failure to declare goods purchased abroad may make you liable for fines levied by HM Revenue Customs, as well as Customs seizing the goods. For purchases above the ?340 duty-free limit, the taxes paid depend on the total value. The second link below states that the duty paid on goods in excess of ?553 depends on the type of goods imported, and that you should contact HM Revenue Customs directly to find out what duty would be imposed.

Q: I am looking to control a electrical outlet 120V over my network, Is their a piece of equipment that can do this?: You should look for electric regulator. and pick up the one of your choice.

Q: As your career develops, what opportunities open up for the senior engineer with experience in Electrical or Electronics Engineering?: Engineers have all doors open to them in both the technical and managerial aspect. With Electrical or Electronics Engineering, you can become a manager of any IT firm or any electricity company. All electrodomestic equipment require as well some sort of electric department which should be ran under an electrical engineer. Construction companies also use electrical engineers to map circuits in houses. Engineers are also suited for business administration and are even preferred over people who studied business management because of their technical knowledge and analytical thinking.

Q: EMP is disruptive energy from nuclear weapons that destroys all electrical equipment. It will take out our power grid, car ignitions, refrigeration, infrastructure, and water purification plants (no electricity, no running water, no infrastructure).So if EMP destroys the whole world's infrastructure in a massive was, how long would it take to re-build? Keep in mind that in that scenario, there WILL be shortages of food and water, there WILL be anarchy, there WILL be survival of the fittest, there WILL be massive fallout, but there will also be a small handful of government officials and scientists hiding in bunkers.So how long would it take to rebuild the infrastructure and cities completely after an EMP nuclear war?: well an EMP ad a nuke arent completely the same a nuke blows everything up while an EMP disables all electric items so if we get hit by a nuke or many nukes, probably 20-30 years
