Purpose: Shackles type SK are used to form an articulated chain connection in the suspension of self-supporting optical cables (OKSN) or optical ground wire cables (OPGW). They enable the transition from one load type shackle to another (higher or lower) load range shackle through a chain connection. Manufactured according to technical specifications TU 3449-001-52819896-2010.

Technical Specifications:

• SK-70-1B: weight — 0.42 kg; breaking load — not less than 70 kN.
• SK-120-1B: weight — 0.905 kg; breaking load — not less than 120 kN.

Application: Shackles type SK are used in communication and power transmission lines to ensure reliable articulated connections of suspension elements of optical cables, allowing for effective load distribution and durability of the structure.
