Purpose: Designed for anchoring self-supporting optical cables (OKSN) on supports of overhead power lines (OPL) with voltages ranging from 35 to 220 kV.

Technical Specifications:

• Nominal outer cable diameter: 8–22 mm.
• Diameter increment: 0.5 mm.
• Maximum tensile working force of the cable (Pmax): 20, 30, 40, 50, 60 kN.
• Clamp length (L): 1800–2500 mm.
• Clamp weight: 2.0–5.0 kg.

NSO-A2 spiral clamps are manufactured in various modifications to ensure the retention of the optical cable under maximum tensile force. Clamps are selected from the following breaking load series: 20, 30, 40, 50, 60 kN. The maximum deviation in the optical cable diameter is ±0.5 mm. Climatic version — UHL 1 according to GOST 15150.
