72000

[Jermale Kunstler]

TheMasoneilan 72000 Series is a fabricated angle valve for precise capacity control while efficiently reducing noise and outlet velocities using single or multiple cages in high capacity and high-pressure letdown gas applications.

The flexibility of a fabricated valve body enables custom-engineered solutions, including large differences between the inlet and outlet sizes to handle downstream gas expansion and noise attenuation. The Masoneilan Lo-dB low noise trim and V-LOG Energy Management Trim are available for noise and vibration control in severe high expansion ratio applications. Benefits include:

During the 1960s, French national railway operator SNCF investigated the use of high-power diesel locomotives for heavy express trains on its non-electrified major lines.[1] Following trials of prototype locomotives during the mid-1960s, which were considerably more powerful than any equivalent previously operated by the SNCF, it chose to order 92 locomotives for mixed passenger and high speed freight traffic. Designated CC 72000, the class was a six-axle diesel-electric locomotive.[1]

Each locomotive had one SACM 16 cylinder four-stroke diesel engine of 3,550 horsepower (2,650 KW) driving an alternator whose output was rectified by silicon rectifiers. There were two traction motors, each mounted on a 3-axle monomotor bogie with two-speed gearing.[2] A unique feature of the monomotor design was the choice of two speed settings, which was intended to benefit its dual use on both freight and passenger services; selecting the 85 km/h max speed 'regime marchandises' maximized tractive effort (beneficial when hauling heavy freight trains), while the 140/160 km/h max speed 'regime voyageurs' was suited for higher speed express trains.[1]

The cab design provided enhanced collision protection for its crew, but otherwise followed traditional practices.[1] The exterior of the locomotive originally bore the operator's standard blue and white livery, produced by designer Paul Arzens.[1]

In addition to the domestic production run, Alsthom marketed the locomotive to the export market. These efforts led to 14 locomotives closely resembling the CC72000 being built for Morocco in 1969, numbering them DF100-114.[1] In 2006, Moroccan operator ONCF procured six redundant CC72000s from SNCF to supplement their existing fleet, renumbering these as DF115-120. In Morocco, they have been operated for freight and passenger services on non-electrified routes.[1]

During the early 1980s, the Portuguese Railways procured a batch of 13 CP Class 1900 and 17 CP Class 1930 locomotives, which had a strong family resemblance to the CC72000.[1] These locomotives were locally manufactured by Sorefame having secured a production license arrangement with Alsthom. The Class 1900s were tasked with heavy freight work, while the slightly faster Class 1930s performed express passenger services.[1]

The type was manufactured at Alsthom's works in Belfort, eastern France, between 1967 and 1974. On 20 December 1967, the first CC 72000 was delivered to SNCF.[1] As more examples followed, the locomotive was initially operated upon the main lines to Brittany in the north-west; it soon began to replace both less powerful diesels and many of the remaining express steam locomotives.[1] The type operated services across the national network, including those between Nantes, Bordeaux and Toulouse in the south-west, between Lyon, Mulhouse, Geneva, Annecy and Grenoble in the east; as well as the core Paris to Clermont-Ferrand route. The final unit was delivered on 21 June 1974.[1]

Throughout the 1970s and 1980s, the SNCF continued its policy of railway electrification, which resulted in a gradual but permanent decline in the need for diesel-hauled express passenger services.[1] Accordingly, the CC72000s were often transferred to new areas, as well as being increasingly used for freight traffic. Despite this progression, the type was heavily used well into the 2000s on various lines, including Dijon-Reims, Paris-Laon and Amiens-Calais, for passenger services.[1] After new SNCF Class BB 75000 diesels began arriving in 2006, as well as a general drop in freight traffic around this time, the type began to be permanently withdrawn. By early 2010, only four original CC72000s remained.[1]

The Sandberg Survivor Powerbank 7in1 72000 really deserves its name. It is a reliable companion for anyone who is on the road for several days without access to power sources. Whether at festivals, camping or other outdoor activities - this power bank reliably supplies energy and offers real added value with its additional functions such as the flashlight and the 12V connection. We can recommend it without reservation and look forward to having it with us on our adventures in the years to come.

Sandberg Survivor (72,000 mAh) has been named the test winner as the most powerful and best power bank on the market, in relation to price and size. This is the ultimate emergency charger for those of you who are going on a trip over several days, or who will be carrying a lot of electronic equipment with you. With a fully charged battery, the power bank can quickly charge an iPhone 13/14 up to 14 times, but it is also powerful enough to supply a laptop, a coffee machine or a small refrigerator that runs on 12 Volts.

The Survivor Powerbank 7in1 72000 not only impressed but also convinced us in our test. Its compactness with a power of 72000mAh makes it a remarkable powerhouse. The variety of connection options opens up a wide range of possible uses for the user. The Survivor Powerbank 7in1 72000 is not only limited to charging smartphones, but can also power other devices such as laptops or e-bike batteries with ease. This flexibility makes it an all-rounder in the world of power banks.

Huge power, charges multiple devices, can be charged with both traditional power and via solar cells, smooth wireless charging, solid and durable construction, included adapters that fit most laptops or other external devices, 12V car socket for more demanding devices, good little bag for belt attachment. Unbelievably impressive. Without a doubt, this Powerbank is the most versatile, portable, extra power solution we've ever tested in terms of uses and power.

You can charge almost anything with the power bank. It has fast charging with QuickCharge for many Android phones, and it supplies power to your laptop via USB-C PD. If your laptop can't be charged via the USB-C port, a set of 12 converters for different computer brands is even included. The Survivor Powerbank 7in1 is an excellent powerbank.

In the end, I tested the power bank with several devices, from a modern Dell XPG 13-7390 laptop, where I used it to charge with a modern USB-C port, as well as an older laptop using the supplied adapter, to a classic mobile phone including Qi wireless charging. I didn't experience a single problem the whole time, even when I was charging three devices at once. Of course, you have to take into account that the power bank will discharge very quickly in this case. And if you add solar panels to it, you can be fully self-sufficient. If I take into account what the power bank can do, how it is processed and the fact that the manufacturer gives it an above-standard warranty of 5 years, I have no problem with this price and I warmly recommend it to everyone.

we can say that the Sandberg external battery is a very good opportunity to stay in nature for a long time, but without losing our favorite devices. At the same time - with a very good ratio between price and quality. It is water, dust and shock resistant, and is an excellent solution for anyone who has problems with the battery life of their mobile devices. With its great power, the power station gives freedom to its owner, including during long treks in the mountains or staying in a place far from civilization.

Based on the technical experience, I was very skeptical about this power bank, but was taught better and am now really excited! If you go for something exceptional, you should really think about the Survivor Powerbank 7in1 72000.
