Modular insulating sticks PMP type consist of one or more elements (modules) that can be connected to obtain a complete equipment.
Modular insulating sticks are provided, according to certification tests, with ‘’RO bayonet’’ socket coupling system, which can be adjusted in two positions: fixed or articulated (when a 5-6° inclination is allowed for the coupling system towards to the stick axis). Upon the client’s request, sticks can be provided with other coupling systems (’’hexagon 12’’, ‘’universal’’, etc.).
These sticks are recommended for the applying of phase clamps of short-circuiting devices on flat bars in indoor installations, on round conductors in outdoor substations and on medium or high-voltage overhead conductors. both in dry conditions and in wet conditions, but only up to 110 kV.
Modular insulating sticks include insulating tubes made of Glass Reinforced Plastic (GRP) with 42 mm diameter.
