OW or OPD cable differences - OW or OPD cable for the garden extension cord

Welcome
I want to make a wall extension for supplying concrete mixer or migomatomat. Approximately 50m long, 3x2,5
In one warehouse I was recommended OW 3x2.5 and in another OPD 3x2.5
What is the difference between these wires and which one is better ?. I also found no difference between OPD and OnPd

OnPd 450 / 750V cable (H07RN-F) 3x2.5 H07RN-F - harmonized cable (H), for rated voltage 450/750 V (07), with insulation made of natural or synthetic rubber (R) and a tire made of chloroprene rubber ( N), with thin copper wire (F)

OW 300 / 500V cable (H05RR-F) 3x2.5 H05RR-F - cable made according to the harmonized standard (H), for voltage 300 / 500V (05), with EPR rubber insulation (R) and EPR rubber coating (R ), with flexible wires (F)
best regards

I would buy this OnPd 450 / 750V (H07RN-F) 3x2.5 H07RN-F
because it has better insulation.

They do not belong, but today there will be a mower and tomorrow a welding machine.
These orange garden crap should disappear from the market!
They often go to construction.
When I meet such a thing at the construction site, I give 15 minutes time for the extension cord to disappear and then the hatchet moves. I turned the voltage off sooner.

Because you are writing such nonsense. Still write to mount sockets without protective contacts where "only" will only be used device in the 2nd class.

The charms of the E-type socket standard, in which you can easily insert the plug of the device in protection class I into the socket without a protective contact will be reflected for decades, if not centuries.

Orange is also cool ( ) H07BQ-F

ha ha colleague mentioned that H07BQ-F is cool and I bought a 30 m OPD 3x2.5 good plug and 16A plug (rubber price almost 40 PLN for the set) and when I returned I went to another warehouse and there a beautiful extension KERG HO7BQ - F 3G 2.5 30 meters only 568 PLN barrier price !!! But the quality is great and the beautiful blue cable. I had to make a jeszce 15m extension with H07BQ-F but in wholesalers they make eyes and they do not have such a cable. What does H07BQ-F have compared to OPD H07RN-F?

I will not change my mind because what you are smiling or not smiling, my friend Wójcik, does not matter.
After purchase, these extension cords start living their own lives. And no one will force the user to have separate extension cords for receivers in protection class I and II. One is always enough.
But you can buy yourself a friend Wójcik petrol lawn mower.

This is not about those who read because they are overwhelmingly aware of the difference between two and three veins, but about those who do not read and are convinced that they know everything.
Because if the device works it is ok.

Calmly, with the eyes of my imagination I can already see breaking the plugs of protective contacts so that they only enter the socket without the appropriate hole. This is the case in countries where such standards preventing the connection of a Class I device to a socket without PE are used, which is why it would be the same in Poland, if not worse (taking into account our tendency to "cope").

The only effective solution is to eliminate installations (and sockets) without a protective conductor, together with such extension cords.
By the way, I don't know why extension cords without PE are still on sale. Due to such inventions in the country, probably a whole bunch of devices work without protection, despite the fact that the socket in the wall has a protective contact.

You might as well write to eliminate devices made in the first class of protection and there will be no problem with sockets and extension cords.

A great conclusion

At the construction site (and not only) my friend, this crap must not be used even if it will be used by a 2nd class device. Do you know why?
Just do not write that the life of a qualified employee (plus compensation) is more worth than the life of a person working in his garden, who used a two-wire extension cord to power the receiver in protection class I and suffered an electric shock.

I suggest nothing to man.
I just express my opinion that two-wire extension cords should disappear from store shelves, because after purchase they are often used for purposes other than those intended, which can lead to electric shock. Just enough.
And I hope that they disappear just as the sockets without protective contact disappear.
And your examples to prove that without these extension cords the world will no longer be the same are completely senseless.
You have no arguments for their defense other than convenience.

Please return to the topic.
