Re: Porcelain wire insulation segments?

Alternating current is actually less efficient in transmission than direct current, which is why some long-distance transmission lines use direct current. However, transformers operate far more effectively and efficiently with alternating current, and the ability to increase and decrease the voltage...

Re: Porcelain wire insulation segments?

The reason for the shift in topic was because I was just trying to find a practical use, which lead to scaling down. Originally it was about wiring in the attic with 6 inches of porcelain every 32 inches of rubber. That would be difficult to manufacture or transport in a coiled form.

Re: Porcelain wire insulation segments?

The only instance this would be appropriate would be like in a computer power supply. The voltage is to be whatever it will be, it is short and can have straight segments, it isn’t too much more fragile than an HDD, and it won’t cause a fire as other components like the CPU would be much hotter.

Re: Porcelain wire insulation segments?

For house wiring, the voltage is not restricted to what the devices can use when designed for a country with 120 volts. There could be transformers at each outlet, which are just copper coils and magnets. Even in the USA, houses receive 240 volts from the distribution transformer, and the circuit br...

Re: Porcelain wire insulation segments?

So thinner wires generate more thermal energy in total, not just rise to a higher temperature? This isn't a several hundred foot span between utility poles, it's like a short, low-power electricity rod, and wherever there is no porcelain there is rubber.

Porcelain wire insulation segments?

Whenever designing a large electrical system it is depressing how much copper wiring it uses. If the wires could be cooled more effectively, then the wires would not need to be as thick. Most electrical insulators are also thermal insulators. An exception is porcelain, which is an electrical insulat...

Re: Looking for a bathtub & shower faucet with separate temperature lever

Also, in the USA, the Uniform Plumbing Code prohibits shower faucet systems that are not either Pressure Balancing or Thermostatic (temperature balancing). That means ball faucets and separate hot/cold faucets are prohibited here. That's not something I am disappointed about, because ball faucets ru...

Re: Looking for a bathtub & shower faucet with separate temperature lever

It does not need to be Made in USA, but that would be preferable. The system would need a faucet/spout, but that can be a separate product. Whatever it is, it would be preferable for the flow to be smoother instead of choppy. There are maybe 6 options besides Delta (which is the prominent option), b...

Looking for a bathtub & shower faucet with separate temperature lever

I have been trying to find a new bathtub & shower faucet that has separate levers for volume and temperature. There is absolutely no name for this type of faucet, so it is difficult to consider every option. It is not the single-handle faucets that need to be raged to warm, and is not the two-handle...
