In the past few days, I have always seen people who want to make cables, and they want to be small cable workshops. To be honest, I didn't produce it, but when it came to making street lights. Sold over.
The value of the cable is very high. Because copper is tens of thousands of dollars a ton, which is twenty times that of steel (now gone). A kilometer of street light cable can be used for hundreds of thousands or even millions.
Not to mention the value of high-voltage cables. But the state has strict requirements for this industry. The threshold is also quite high.
You also need millions of funds to buy equipment in the regional market, and you can only build the most basic household lines. This is a matter related to the safety of life, and the state still strictly controls it. The profit of the international first-line manufacturers may be 10 points, but the domestic ones can have 8 points, such as the Far East.
It would be nice for the average brand to have 5 points. For small workshops, it's even more difficult... If you don't understand anything, a complete layman, and you want to do this, or venture capital, then it's not interesting.
You better start with being a salesman in the cable division. There are also one or two pips of profit. A good salesman is much stronger than a small factory.

If you can memorize some famous poems, put them in, but make sure it fits the meaning.
I also need to write more figurative sentences or something.
Well, it's a little more complicated like this.

i=p (, the power factor is taken, if you really are a pure resistive load you can take 1, then the current is 182A. The current carrying capacity of the conventional 10mm2 copper core cable is 61A when it is laid directly in the ground at 30°, and it is enough to use 4 10 square cables at the same time, considering the protection of electrical appliances (the tripping current of the circuit breaker or fuse is set to 200A).
