Class D of the IEC-60831, the low voltage capacitor manufacturing standard, sets a maximum working value of 55\u00baC, but the strength of the <strong>CIRCUTOR Heavy Duty<\/strong> capacitor enables capacitors to work in extreme temperature conditions, occasionally supporting up to 65\u00baC, with this beings another key feature ensuring 150,000 h of useful life.

In this regard, <strong>CIRCUTOR Heavy Duty<\/strong> capacitors are equipped with a pressure relief protection system, which acts in the event of an increase in its internal pressure simply a higher value than 506 hPa approximately (0.5 bar), disconnecting the capacitor from the mains as shown in the figure 2.<\/p>\n<h6 style=\"font-size: 11px; text-align: center;\"><img loading=\"lazy\" class=\" size-full wp-image-192\" title=\"Figure.2  The CIRCUTOR Heavy Duty capacitors have an overpressure protection system which is activated in case of any increase in internal pressure, disconnecting the capacitor from the network.\" src=\"https:\/\/circutorweb.atic.blue\/wp-content\/uploads\/2014\/07\/Article-HeavyDuty-sobrepresion.jpg\" alt=\"Figure.2  The CIRCUTOR Heavy Duty capacitors have an overpressure protection system which is activated in case of any increase in internal pressure, disconnecting the capacitor from the network.\" width=\"55%\" height=\"NaN\" \/><br \/>Figure.2&nbsp;<br \/>The CIRCUTOR Heavy Duty capacitors have an overpressure protection system which is activated <br \/>in case of any increase in internal pressure, disconnecting the capacitor from the network.<\/h6>\n<h4>Manufacturing: a vital step for quality<\/h4>\n<p>The figure 3 at the next page shows the main components of the capacitors filled with <strong>CIRCUTOR Heavy Duty<\/strong> gas.<\/p>\n<h6 style=\"font-size: 11px; text-align: center;\"><img loading=\"lazy\" class=\" size-full wp-image-193\" title=\"Figure 3\" src=\"https:\/\/circutorweb.atic.blue\/wp-content\/uploads\/2014\/07\/Article-HeavyDuty-figura3-en.jpg\" alt=\"Figure 3\" width=\"55%\" height=\"NaN\" \/><br \/>Figure 3<\/h6>\n<p>Its manufacturing process includes the basic premise of any product manufactured by <strong>CIRCUTOR<\/strong>: maximum guarantees of quality and reliability. This means that the capacitor production process includes some aspects that are worthy of mention:<\/p>\n<table>\n<tbody>\n<tr>\n<td style=\"width: 60%;\" valign=\"top\">\n<ol style=\"text-align: start;\">\n<li>Once the coils are mounted inside the aluminium tube, it is vital to ensure the total elimination of any possible humidity from their components, so each capacitor undergoes a long and exhaustive vacuum process in autoclaves. It is essential to ensure that there is no trace of humidity or oxygen left inside the capacitor to prevent oxidation of the metallic part of the polypropylene film. Preventing this oxidation also avoids rapid deterioration of the capacitor and therefore reduces its dielectric losses, lowering internal discharges and improving its capacity throughout its lifetime.<\/li>\n<li>After the vacuum process, the capacitors are filled with a mix of N2 (nitrogen) and He4 (helium gas isotope with an atomic mass of 4, a natural element which has a very low density and is colourless, odourless and flavourless) gases, once again under vacuum conditions, until achieving an internal pressure in the capacitor of slightly more than 1013 hPa (1atm). The figure shows this filling process.<\/li>\n<li>As can be seen in the figure, during the filling and sealing process of the capacitors, the cover is already equipped with the set of terminals for connection to the mains. These terminals already include the discharge resistors required to discharge the capacitor to a value of less than 75 V three minutes after it is disconnected from the mains (figure), as specified in the applicable standard <strong>IEC 60831-1<\/strong>.<\/li>\n<li>The production process ends with the performance of a basic test to guarantee the quality and reliability of each capacitor: checking the sealing process to ensure that there are no leakages of the internal gas. If any leakage is detected, that capacitor is removed from the production process.<\/li>\n<\/ol>\n<\/td>\n<td align=\"center\" valign=\"top\">\n<h6><img loading=\"lazy\" class=\" size-full wp-image-194\" style=\"margin-left: 10px;\" title=\"Figure 4 apacitor filling and sealing process\" src=\"https:\/\/circutorweb.atic.blue\/wp-content\/uploads\/2014\/07\/Article-HeavyDuty-figura4.jpg\" alt=\"Figure 4 Capacitor filling and sealing process\" width=\"172\" height=\"241\" \/><br \/>Figure 4.&nbsp;<br \/>Capacitor filling and sealing process<br \/><img loading=\"lazy\" class=\" size-full wp-image-195\" style=\"font-size: 1em; margin-left: 10px;\" title=\"Figure 5 Terminals for connection to the network\" src=\"https:\/\/circutorweb.atic.blue\/wp-content\/uploads\/2014\/07\/Article-HeavyDuty-figura5.jpg\" alt=\"Figure 5 Terminals for connection to the network\" width=\"171\" height=\"172\" \/><br \/>Figure 5.&nbsp;<br \/>Terminals for connection to the network<\/h6>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h4><span style=\"font-size: 1em;\">Conclusions<\/span><\/h4>\n<p>In summary, we can highlight the strength of the Heavy Duty capacitors, a reliable unit that permanently supports <strong>1.8 times the rated current<\/strong> and up to <strong>2.5 times RC for short time<\/strong>, reaching an inrush current of up to 400 times RC, and guaranteeing a long lifetime of up to <strong>150,000 hours<\/strong>.
