Vysoká pohotovosť a efektívnosť elektrického napájania s vákuovou technikou
Či v elektrárňach a transformačných staniciach, lokálnych rozvodných sieťach, na lodiach alebo vo vlakoch, rozvádzače a prístroje na prevádzku sietí vysokého napätia možno nájsť v najrozmanitejších aplikáciách. Naše komplexné portfólio komponentov vákuovej spínacej techniky na inštalovanie do vzduchovo izolovaných vysokonapäťových rozvádzačov zabezpečuje pritom trvalo spoľahlivý a bezpečný rozvod elektrickej energie.
Always reliable
Vacuum interrupters are the centerpiece of our medium-voltage components. The hermetically sealed vacuum contact gap keeps the switching characteristics of the interrupters constant throughout their entire lifecycle. Special contact materials made by Siemens ensure that our vacuum interrupters offer absolutely top performance. With valuable features that include high short-circuit switching capacity and minimum forward resistance, they ensure reliable switching even under difficult environmental conditions – like vibration and fluctuating frequencies – regardless of whether they’re installed horizontally or vertically. Our vacuum interrupters can perform up to 30,000 operating cycles when used in circuit breakers and up to three million for contactors – maintenance-free, throughout their entire service life.
A high level of availability and long service life – these are the determining criteria when selecting medium-voltage switching devices. That’s one of the reasons why more than 70 percent of all network operators choose vacuum switching technology today. Hermetically sealed vacuum interrupters guarantee consistently high quality throughout the entire product lifecycle. There’s little wear, given the extremely low arc voltage, just like the minimum energy conversion in the contact gap – thanks to the short arcing time. The very low contact resistance prolongs the product’s service life and keeps maintenance requirements to a minimum.
Our medium-voltage components are comprehensively based on vacuum technology and comply with all current national and international standards. These devices can be used in almost all medium-voltage power distribution applications and can be adapted for other specific requirements as appropriate. You’ll benefit from a high level of reliability, flexibility, and cost-efficiency.
