Sarel Srl products

The IM6 Series of on-load switches from Sarel Srl are designed for medium voltage applications, operating within the 12 to 36 kV range. These switches feature an epoxy cast resin housing, filled with pressurized SF6 gas at 150 kPa to ensure a sealed operative life. The switch's mechanism involves movable contacts on an insulated rotary shaft within the robust cast resin body. Fixed contacts are directly mounted onto the housing, and the rotary motion is controlled by a front-operating mechanism. The switch delivers reliable performance with three available positions: close, open, and earthed, supported by a robust locking system that minimizes operational errors. With notable characteristics such as extended service life, maintenance-free active components, and enhanced safety during operation, this series is suitable for applications requiring rated voltages from 12 to 36 kV, and short-circuit currents up to 25 kA. The IM6 Series accommodates rated frequencies of 50-60 Hz, with a peak current capability of up to 62.5 kA.

The WL series is a range of medium voltage vacuum circuit breakers designed for indoor use. These breakers incorporate a unique separate pole technique where each pole contains a vacuum interrupter encapsulated directly in resin during the moulding process. This method ensures enhanced protection against impact, dust, and condensation, providing a durable and reliable solution. They can be controlled remotely using various electrical accessories such as geared motors and shunt opening releases. The circuit breakers are structured on a compact, sturdy metallic frame without wheels, resulting in a lightweight design. With rated power-frequency withstand voltages of up to 70kV, lightning impulse up to 170kV, and breaking capacities reaching 20kA, these breakers are built to handle demanding electrical applications. They operate at standard frequencies of 50-60Hz with a rated current up to 1250A, suitable for multiple industrial electrical environments.

SYStem6 medium voltage switchboards are crafted with a standardized, modular, and compact design, making them suitable for a range of complex electrical configurations. The switchboards boast an enclosure that is both protected and arc-proof, classified as LSC2A-PI. Key components include SF6 insulated on-load switches and vacuum circuit breakers. Designed to ensure the operator`s safety, each panel is outfitted with mechanical interlocks and visual mimic diagrams. The switchboards cover a rated voltage spectrum of 12 to 36 kV, with power-frequency withstand voltage ratings up to 70 kV and lightning impulse withstand voltages reaching 170 kV. They operate at frequencies of 50-60 Hz, with main bus bar currents up to 1000 A and functional units up to 630 A or 1000 A. The switchboards can withstand short-circuit currents of up to 25 kA for specified durations and feature internal arc protection up to 16 kA for 1 second, with protection degrees of IP2X internally and IP3X externally.

This mobile substation is housed within standard or high cube 20 or 40-foot containers, tailored to accommodate the specific equipment it houses. Transport is streamlined by utilizing processes standard for container handling. The interior of the container is systematically divided into three distinct compartments, comprising a medium voltage switchboard, a low voltage switchboard, and a transformer. Each section is independently secured with specialized safety locks, ensuring controlled access. Intricately designed security mechanisms restrict access to the transformer compartment, especially when the transformer is active, to maintain safety protocols. This setup is suited for areas requiring temporary or flexible electrical infrastructure, offering robust and reliable solutions across various applications.
