Production description:
(1) Anti-corrosion, waterproof, low temperature rise, low noise, easy installation, no maintenance;
(2) It uses all-sealed structure. The exposed part of high and low voltage terminal is separated from surrounding by imported sealant waterproof material. It is placed in the pit when installing. And it still works safely when the pit is immersed or the transformer is submerged. It can resist flood water disaster for effectively improving the reliability of power-supply system.
(3) Low voltage switchgear uses patent outdoor light box-type protective casing. Both sides of the casing can install all-day poster board. It uses small volume, green economic LED light-emitting component
- Q: I'm 14 and I go to a technical highschool, I'm in hvac because I missed electrical by 1 person, if I get the chance should I switch to electrical? I already have my tools and uniform.
- What interests you the most? There is employment in both fields, and both pay good. You'll have to be a journeyman, no matter what before you get a master's license. I would frankly stick with HVAC because you will learn electrical stuff as you go along. I worked as a technician on food service equipment and vending machines for 20 years. There are a LOT of HVAC technicians and refrigeration technicians who also hold electrical licenses, but very few electricians who have licenses in any other area than electrical.
- Q: hi i have a black glass tv stand which makes the dust very visible, i normally wipe with a cloth, but i don't really want to do this like every time it piles up with dust, is there a thing which removes dust automatically (please give me a link either OKorder or which supports pay-pal) thank you
- You could turn your Living room into a clean room, and put on a bunny suit every time you go into it!
- Q: I have all my electrical equipment hooked up to 1 HDTV, that is sky, ps3 and computer. Today i noticed that when i change the input mode while booting my computer there is an option next to RGB. This option is either PC or DTV depending on which one i select, what is this? and also which is better?
- The two choices are PC Personal Computer or DTV Digital TV. Depending on what you're doing will determine the mode of operation. When in TV mode you use the TV controls to set the width and aspect ration of the display. When you're using the PC the graphics card will normally set the width and aspect ration. Ever notice that when you change resolution on a normal PC monitor that 640X480 uses just as much screen as when it's set to 1072X768. The graphics card adjusts the size. DTV mode will have the internal controls in your TV controlling the size and PC will have the graphics card in the PC controlling it. As I'm writing this another possibility came to mind. You may have an ATSC tuner (digital tuner) built into your HDTV. The TV may simply be asking you which source you want it to look at. In other words do you want to continue watching TV using the internal tuner or switch to looking at the PC information that is now available. Your best bet is to pick up the owners manual and read the section that tells you about hooking up your computer to the monitor. I'm sure that will explain what your asking for.
- Q: I know converters exist, but are they safe for high end audio equipment?I have a digi 002 rack, grace M101, and great river pres.would a power conditioner help me?
- Pull out the bottom prong. It is safe, and in almost no way affects your device. The third bottom prong is to make sure the device doesn't shock you. You'll be fine without it.
- Q: I am undecided whether I want to become a Electrical Engineer or a Master Electrician. I know that Master Electricians can start their own business (Contractor) or take responsibility on a project. Electrical Engineers are the ones who design electrical equipment and that design the electrical projects. I am just curious of which career would have more opportunity to make more salary. I also would like to know if an Electrical Engineer can also be a contractor like the Masters electricians. Country: USA
- I've been fortunate enough to be on both sides of this fence and I will say being an EE is the way to go. To become a Master Electrician you will have to go through first becoming a Journeyman Electrician. This usually requires a minimum of 4 years of work without an Associates degree, 2 years of work experience with an Associates degree or 1 year of experience with a BSEE. Then after you have had your Journeymans license for a year you can then take the test to become a Master Electrician. Thats how its done in my state, yours may be different. With any of them though you just can't come straight out of school and be a Master Electrician. I started out life wanting to be an electrician and got my Associates degree in Electrical Technology to do so. I worked as an electrician for 2 years before I went back to school and got my BSEE. Both are respectable jobs but I really like my engineering job a lot more, my back likes it a lot more too. Personally my starting salary as an EE was more than was paid to the Master Electricians at the first electrical contractor I worked for. Remember though, money isn't everything!
- Q: how we can justify or design the voltage rating of any electrical equipment. some motors are 415 v, others are 11kv, 33 kv, motors. ofcourse the current rating will change as per voltage rating. but at what stage of power rating this voltage will change as any standards.
- Motors are designed for the lowest voltage that is practical based on the wire size required at a given power level. Wire size is an issue from the standpoint of the wire feeding power to the motor and the wire used for the coils inside the motor. Since it is inconvenient for users to have factories and other facilities wired for several different voltage levels, there is a market demand for motors designed for higher voltages than would be necessary based on wire size. Therefore, there is considerable overlap of the motor power ranges offered for sale at any given voltage level.
- Q: I just heard tapping noises coming from the back door. The back door leads to the laundry room and multiple storage rooms. There is also all the heating and electrical equipment down there. The leak is coming from a pipe at the ceiling in a storage one, the room beside all the electrical equipment. The floor is soaked and the water is leaking a lot. Am I in danger?
- Are you in danger only if the water comes in contact with electrical wires yes have the pipe repaired call a plumber don't wait til Monday when it will be cheaper because it won't when the ceiling collapses some one may get hit with plaster board and the. You wind up with an even bigger hole . The longer you wait the more it will cost. Especially if a fire were to start remember water and electricity don't play well together some one can be electricuted
- Q: (hairdressing)
- Anything you'd like to use. Conditioner isn't exactly dangerous.
- Q: for a store of electrical equipments, I want to create a database for it, what is the data that I should maintain in this database (the names of the columns)?
- You need multiple tables. Using int() auto_increment primary keys for linking each section of data you want something like : stock_codes ( id int(6) primary key auto_increment, stock_code varchar(45) unique key, stock_description varchar(45), stock_qty int(6), suppler_id int(6) ) stock_movement ( id int(6) primary key auto_increment, in_date date, out_date date, moved_qty int(6), stock_id int(6), ) It helps to have tables of suppliers details, client details, sales person details, department details etc. If items have possible alternative suppliers you dump the supplier_id from the stock codes and use a link table for the stock id and supplier id to identify each inward transaction. Add tables for any additional information using links from the other tables to co-ordinate the data.
- Q: i have an old distribution board, dorman smith and the lights are all off one circuit, when i flicked the outside light on it knocked off all the lights but didnt trip the 6amp circuit breaker?? Has the circuit breaker had it? its at least 10 years old?
- Sounds like a fire waiting to happen. You should update. If you cant do this you might want to look into adding more circuits to you system but not a 6amp lights on a normal run should be 15amp if you are not good with this and do not know about electrical systems you might want to have some one come in and look. Home owners love to do it them selves but please think safe and with your older systems it wouldn't hurt to ask for a free Quote and then you would know what needs done. Good luck.
