High Voltage Equipment

¿Por qué usar seccionadores de HAPAM?

  • Mas de 75 años de experiencia
  • Diseño durable y fiable
  • Mas de 30.000 seccionadores y cuchillas de puesta a tierra Actualmente en servicio en mas de 80 paises   de todo el mundo
  • Virtualmente libre de mantenimiento.

Cuchilla principal

La cuchilla principal está fabricada con un tubo de aluminio y contactos de cobre cubiertos con plata en ambos extremos. Durante el cierre del seccionador, la cuchilla principal efectúa un doble movimiento: primero, la cuchilla principal desciende hasta que alcanza una posición completamente horizontal y entonces gira de modo que la presión de contacto se aplica en ambos extremos del seccionador.

Los contactos principales son de diseño “ lazo invertido “ lo cual los hace adecuados para corrientes de cortocircuito muy elevadas. se proveen pantallas anti-corona.

Cuchillas de puesta a tierra

Los seccionadores Hapam pueden ser equipados con cuchillas de puesta a tierra, instaladas al lado derecho y/o izquierdo.

La cuchilla de puesta a tierra consiste de un tubo de aluminio, provisto con contactos recubiertos de plata en ambos extremos.

Current and Potential Transformers

Current Transformers for Outdoor Use

Current transformers are used in high-voltage networks in the range of 24 -550 kV. They transform high currents to standardized values for meters and protection and measuring devices.

Technical Characteristics:

  • Paper-Oil and SF6 Gas Insulation.
  • From 24 to 550 kV.
  • Minimal oil volume, high grade mineral oil and PCB-free.Instrument transformers (CT/PT)
  • The active part is located in the transformer head enclosure.
  • Fine graduation nozzle.
  • Stainless steel expansion bellows
  • Ratio change through primary (optional Secondary).
  • Housing explosion tested.
  • Precise control of the electric field and prevention of local partial discharges through the fine graduated nozzle.
  • Increased safety by preventing subsequent arching formation.
  • High operational safety, as there are no live parts in the isolator.

Type

  • JOF T (24 -123) kV Outdoor Use, insulated in Paper - Oil
  • JOF (24 - 550) kV Outdoor Use, insulated in Paper - Oil
  • JGF (245 - 550) kV Outdoor use, insulated in SF6 Gas
