ApplicationThe ABB ITD Inline Tension Disconnect Switch is a single-phase,hookstick-operated switch used to manually switch de-energized orparallel circuits of overhead distribution lines rated 15 through 38 kV,150/200 kV BIL. The ITDs are installed directly in the line and are

used to sectionalize the circuit. Switches are selected by continuouscurrent and voltage ratings.

OperationAll ABB ITD disconnect switches include loadbreak hooks. Use theappropriate loadbreak device to open the switch under load. The pull-ring can be utilized for easy opening and ice breaking. The hook por-tion of the contact-casting matches the blade latch for positive closure.

Design Features

Insulators

Silicone insulator provides extra leakage dis-tance and BIL ratings to ensure inline

switches are not the flashover point

Blade Design

Copper blades with stainless steel shoulder

pins. Standard blade opening is 90; 160with stop pin removed

Loadbreak Hooks

Galvanized steel for corrosion protection,to be used with loadbreak tool
