AI Thread Summary
Designing electrical power connectors involves determining parameters such as length and thickness based on required current ratings. The discussion focuses on connectors like tee-connectors and parallel groove connectors used in transmission lines and substations, with materials primarily being aluminum alloy. Test results are available for existing units, but guidance is sought for designing new sizes. A suggestion is made to calculate resistance for a first-level approximation to assess ohmic heating. The conversation emphasizes the need for precise formulas or guiding factors in connector design.

Hello!

I am in design and manufacturing of electrical power connectors. I need to know if there is any precise formula to design a connector, i.e. given the required current rating, is there a particular formula that gives the parameters of the connector, like length and thickness??

All our connectors are made of Aluminium alloy. So resistivity, material density and Specific heat remain constant.

Looking forward for a help...

Do you have test results for your units? Or are you trying to do theoretical calculations to back up what you have?
 
yeh we do have test results. But for newer sizes, we require some kind of a guiding factor for the design...
 
Can you not just calculate the simple resistance and then determine ohmic heating?

EDIT: At least, as a first level approximation?
 

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
