On 21.12.2014, CKD made a comment about the insulation of certain locomotives and Electrical Multiple-Unit Trains.
I am not a specialist in either insulation or electronics. I said that I have travelled on RVR Class 32 at least 44 years old. How is it possible to work for so many years without a proper insulation?
The locomotive VL-8 is now 54 years old. Also poor insulation?
I wrote that the aforementioned two types are very reliable. At least when they are properly maintained.
I never said that they are either modern or as effective as others. I do not believe that everything in the past was good or effective. I agree with the comment of V. Peichev that VL-8 (and indeed RVR) consume more energy than their western analogues, including contemporaries.
The designers of those two types decided that reliability and simplicity are more important than energy effectiveness.
V. Peichev used the phrase “морално остарелия подвижен състав” and I cannot disagree. However, does it mean that the locomotives VL-8 are not reliable?
Does V. Peichev believe that the Diesel Multiple-Train Units “Desiro” will last as long as VL-8 or at least RVR Class 32?
I know that comparing electrical and diesel trains is not fair but what about our Class 7 from Lugansk? Is there anyone who will put a hand on his heart and say that Desiro will last longer than Class 7?
P.S.
The electricity production of Azerbaijan is 22.99 billion kWh.
The electricity consumption of Azerbaijan is 17.79 billion kWh.
It seems there is no deficit…
