Product Catalogue: Disconnectors

CGVB-05 Vertical Break Disconnector up to 550 kV

The Alstom Grid CGVB-05 is a vertical break type disconnector which reduces phase spacing to a minimum.

SX Pantograph Disconnector Up to 1000 kV

The SX is a space saving double scissor aluminium disconnector connecting the lower busbar to the upper one via the pantograph arms. Horizontal rather than vertical separation means a space reduction of as much as 30%.

SPV Semi-Pantograph Disconnector up to 1000 kV

The Alstom SPV is a space saving vertical reach disconnector connecting the lower busbar to the upper one via the semi-pantograph arm. Horizontal rather than vertical separation means a space reduction of as much as 30%.

SPVL Semi-Pantograph Disconnector up to 1000 kV

The Alstom Grid SPVL is a space saving vertical reach disconnector connecting the lower busbar to the upper one via the semi-pantograph arm. Horizontal rather than vertical separation means a space reduction of as much as 30%.

SPO Knee type disconnector up to 1200 KV

The Alstom Grid SPO is a vertical break disconnector with a two-piece arm. In the open position the blade sections fold upon themselves in a vertical plane of only 60% of the longitudinal dimension.

SPOL Knee type disconnectors up to 1200 kV

The Alstom Grid SPOL is a vertical break disconnector with a two-piece arm. In the open position the blade sections fold upon themselves in a vertical plane of only 60% of the longitudinal dimension.

VCB V-Type Centre break disconnector up to 145 kV

The Alstom Grid VCB is a V-type centre break disconnector on which both insulators rotate to open and close the switch. Structural and civil work costs are kept to a minimum thus reducing overall installation costs.

S3CV Vertical Break Disconnector up to 245 kV

The Alstom Grid S3CV is a reduced phase-to-phase distance vertical break switch.

S3C Double Side Break Disconnector up to 300 kV

The Alstom Grid S3C is a low profile, reduced phase-to-phase distance double side break disconnector on which the centre insulator rotates to open and close the switch.

S3CVL Vertical Break Disconnector up to 550 kV

The Alstom Grid S3CVL is a modern, three insulator vertical break disconnector equipped with the unique Alstom Grid “L” Contact.

S3CD - Double Side Break Disconnector up to 550 kV

The Alstom Grid S3CD is a double side break disconnector on which the centre insulator rotates to open and close the switch, and is particularly suitable for installations with low vertical clearance.

S3CVS Vertical Break Disconnector up to 72 kV

The Altom Grid S3CVS is a heavy duty vertical break disconnector suitable for high current installations such as generator busbar disconnectors for power plants, electrical brake generators, SVC plants, as well as feeding furnaces and electrolytic plants.

S3F Vertical Break Disconnector up to 72,5 kV

The Alstom Grid S3F is a medium voltage reduced phase-to-phase distance vertical break disconnector specifically designed for railway applications.

BCVB Vertical Break Disconnector up to 800 kV

The Alstom Grid BCVB is a vertical break disconnector which reduces phase spacing to a minimum.

DSWatch E-Commissioning system for disconnectors

The Alstom Grid DSWatch is a user-friendly and cost effective tool developed by Alstom Grid for the on-site commissioning and preventive maintenance of HV disconnectors, specifically designed to make information recording more accurate.

L Contact

The Alstom Grid L Contact is a maintenance free contact with in-built arcing contacts where both the male and female contacts have been segregated thus ensuring total reliability even under the most adverse climatic conditions.

Motor Operating Mechanism

The primary function of the motor operating mechanism is to provide reliable remote operation of disconnectors by means of a torsional pipe. Alstom Grid mechanisms also provide real position signalisation of the disconnector as well as the necessary operational interlocking functions.
