A 30 kV (kilovolt) voltage rating is applied to a cable designed to operate in an electrical system where the nominal voltage is 30,000 volts.
Waterblocking layers are also commonly specified on 30kV cables where the installation environment may see them in cable ducts liable to flooding or in waterlogged ground. Longitudinal and/or radial waterblocking tapes can provide protection in the event of ingress.
30 kV cable is one of the most popular voltage ratings listed in IEC 60038 (IEC Standard Voltages) and one of those listed in IEC 60502 Part 2: Cables for rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV). Voltage ratings covered by this IEC Standard include:
30kV cables are more commonly unarmoured under standard IEC 60502-2, but the additional protection of armoured wires and tapes can be specified where mechanical protection is required, whether by regulation or installation design.
Im Mittelspannungsbereich hat sich SÜDKABEL als technischer Vorreiter positioniert und baut diese Stellung kontinuierlich aus. Dazu gehört auch das extrem vielseitige Produktspektrum: Das reicht von einfachen Basisprodukten bis hin zu hochspezialisierten maßgeschneiderten Produkten für Spannungsbereiche bis 36 kV.

Designados de acordo com a sua construção, N identifica núcleos de cobre, enquanto NA designa núcleos de alumínio. Estão indicados para instalação no solo, no exterior e em condutas de cabos, com propriedades hidrófugas adicionais disponíveis nos casos em que o ambiente de instalação seja húmido e o cabo possa estar sujeito a arborescência de água.
With the 30kV output wire I could get at low as 4kV but I wanted lower. So by making the FOCUS HV output wire available as an alternative I was able to get the range 1.2kV to 4.6kV. It uses a flyback transformer to step the input voltage up to around 10kV AC and then feeds this into a multiplier which brings it up to around 30kV DC.
Mittelspannungsnetze der regionalen Verteilnetzbetreiber werden im Regelfall in Umspannwerken aus dem übergeordneten Hochspannungsnetz wie der 110-kV-Ebene (Verteilnetzebene) gespeist und dienen der Anspeisung der regional verteilten Transformatorenstationen, welche die einzelnen Niederspannungsnetze zu den Endkunden versorgen. Mittelspannungsnetze dienen …
