SKU: PTU-AS-Un-n-C
Category:

Telescopic insulating sticks (PTU) are made of two or more tubular elements (of various diameters) which can be extended or folded in an undetachable manner.

Telescopic insulating sticks are provided, according to certification tests, with a ‘’hexagon 12’’ coupling system which allows the coupling of other protective devices, adapters or accessories.

Upon the customer’s demand, sticks can be provided with other coupling systems (’’RO bayonet’’, ‘’universal’’, etc.).

Sticks type PTU-20-45-110-C are delivered with a 0.40 m insulating extension handle. These types of sticks can be used for works or operations both in transformers stations and on overhead lines.

The telescopic insulating sticks include insulating tubes made of fibre-reinforced plastic with diameters between 23 and 59 mm.
