NPS as a Line Switch Disconnector

Crossarm installation One of the most common building standards where the line switch disconnector is integrated on the same crossarm as the lines. Wooden poles are most often used for this type of installation.

Installation below live line Some building styles and standards require a separate crossarm below the line crossarm. Sufficient clearances to the pole and between phases can be arranged by the flexible arrangement of phase elements.

Installation above live line A typical installation example above the live line on a steel structure pole.

Vertical installation Used for branching lines down to cables. The vertically installed switch disconnector is also used as a transformer switch disconnector.

Two pole mounting All installation examples are also available for two-pole mounting. Pole fitting accessories for various pole types are also available wooden poles concrete poles steel poles and structures

NPS for Transformer Switch Disconnector/ NPF fuse holder

Fuse holders The NPS switch disconnector can be equipped with several types of fuse holders. The vertically mounted NPS can be used as transformer switch disconnector. The breaking capacity of the whip (25/50 A) is enough for disconnecting a fully loaded distribution transformer up to 800/1600 kVA. NPS24B1-J2 and NPAC5

Fuse holders If the pole element is horizontally mounted the fuse holder for HRC fuses (6.3, 16, 25 A) or (SMIA-KR_) melting fuses can be easily integrated (up to 63 A) to the switch disconnector. The fuses are replaced using isolated rods from ground level. NPS24B1-J2, NPAC9-J2 and NPAF7-J2

Fuse holders NPS can be equipped with integrated earthing contact for open and earthed position. The separate fuse holder for HRC and SMIA-KR_ can also be equipped with surge arresters for one-, two-, or three-phase installation. NPS24B1-J2 NPAE5 NPF24B2

Fuse holders NPS can be equipped with a separate fuse holder for DIN-type fuses (CEF outdoor HRC fuses). IEC 282 ANSI 7.2 kV up to 160 A 12.0 kV up to 100 A 17.5 kV up to 100 A 24.0 kV up to 100 A 36.0 kV up to 40 A 25.5 kV 160 A 25.8 kV 100 A 38.0 kV 40 A NPF24E5

Unique design The unique design on breaking whips and dry type breaking chambers eliminates the risk of oil leakage. Risk of oil eliminated Pollution risk for soil waters Safety risk in case of failed interruption No need to check oil level or compensate for possible leakages Risk of conventional air breaking chambers eliminated by protected breaking contacts Malfunctions due to dust, sand, ice and small animals Risk of terrain fires due to arcing
