Title (EN) FIRE-RESISTANT ELECTRICAL FEEDTHROUGH
(FR) INTERCONNEXION ÉLECTRIQUE RÉSISTANTE AU FEU
Abstract:
(EN) The present invention provides a fire-resistant electrical feedthrough system for use in offshore and top-side electrical submersible pump ("ESP") installations. The fire-resistant electrical feedthrough system includes a minimum of two, redundant pressure barriers, in order to provide for safe operation and increased system reliability. The primary barrier is typically embedded within the wellhead equipment structure, while the secondary barrier is typically externally mounted.
(FR) La présente invention concerne un système d'interconnexion électrique résistante au feu utilisable dans des installations de pompe submersible électrique (« ESP ») en mer et à la surface. Le système d’interconnexion électrique résistante au feu inclut un minimum de deux barrières de pression redondantes, afin d’assurer la sécurité de fonctionnement et d’accroître la fiabilité du système. La barrière primaire est typiquement incorporée à l’intérieur de la structure d’équipement de tête de puits, tandis que la barrière secondaire est typiquement montée de manière externe.
