Spiral vibration dampers of the GVS type are designed to protect conductors, ground wires, and optical communication cables on overhead power lines (OHL) from vibrational stresses. They are manufactured in accordance with TU 3449-009-52819896-2020.

Design and Features
The damper consists of a spiral made from a composite round rod with a diameter of 12–16 mm. The spiral comprises two sections:

1. Installation Section: Intended for attaching the damper to the conductor, ground wire, or cable.
2. Damping Section: Reduces vibration through impacts of the spiral on the protected element.

The nomenclature, quantity, and installation scheme of the products on OHL are determined by specialists from LLC "FORENERGO-ENGINEERING" based on survey forms.
