Grading Capacitors

Product catalog summary

Overview: This document provides technical specifications and features of grading capacitors and coupling capacitors designed for high voltage (H.V.) circuit breakers and coupling capacitor applications ranging from 72.5 kV to 800 kV for outdoor installations. The focus is on quality, reliability, and simplified design.

Specifications:

Insulation: Utilizes synthetic liquid, polypropylene, and paper insulation with ceramic insulators.
Construction: Hermetically sealed, maintenance-free, with external metallic parts made of painted aluminum alloy and stainless steel.
Electrical Features: Rated voltage from 90 to 250 kV, frequency of 50/60 Hz, capacitance ranging from 400 to 4000 pF, and a loss factor of 0.04% at rated voltage.
Environmental Conditions: Operates in ambient temperatures from -40 to +70 °C.

Grading Capacitor Types:

CRP: Designed for spare parts with specific dimensions and electrical features.
FSKm: Available in different types with varying dimensions and capacitance from 500 to 2000 pF.

Coupling Capacitor Features:

Designed for high-frequency telecommunication systems with constant capacitance under all service conditions and no partial discharges.
Complies with CEI/IEC and other international standards.

Installation and Maintenance:

Easy installation and commissioning with a long life cycle and short delivery time.

Contact Information: The document lists contact details for Trench Group's offices in Italy, Austria, Brazil, Canada, France, Germany, and Switzerland.
