High Voltage Disconnector (33KV-765KV)
A high-voltage disconnector is a mechanical switching device that creates an isolating separation in a substation circuit.

Product & engineering
Understand the product.
In electrical engineering, a disconnector, disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance. Such switches are often found in electrical distribution and industrial applications, where machinery must have its source of driving power removed for adjustment or repair.
Centre-break and double-break designs move contacts horizontally; vertical-break and pantograph arrangements use a different motion and required overhead space. The insulators, current-carrying contacts, frame, rods and drive must operate together while maintaining the required separation and clearances. Phase spacing, bus height, mechanical terminal loads, pollution and environmental duty shape the actual switchyard layout.
Disconnecting and earthing have separate purposes. An optional earthing switch connects the specified isolated circuit section to earth, while interlocks and position indications coordinate it with the disconnector and other equipment. Opening a disconnector does not by itself prove that every possible source, trapped charge or adjacent part of an installation is absent.
Some designs have specified duties for bus-transfer or induced-current switching. Those assigned capabilities should not be confused with general load-breaking or fault-clearing capacity. Selection therefore considers the actual switching duties, insulation requirements, drive and control interfaces, as well as the voltage band shown in the report title.
What turns activity into demand
A disconnector's installed value comes from a workable isolating arrangement, not simply from the length of its open gap. The family covers high-voltage isolating devices within the named band. Earthing switches, operating drives and control cabinets may be supplied with them, but circuit breakers and an entire substation are distinct products or project packages.
The commercial boundary
The family covers high-voltage isolating devices within the named band. Earthing switches, operating drives and control cabinets may be supplied with them, but circuit breakers and an entire substation are distinct products or project packages.
