Supporting clamps of type PG-30/12-20 SIP are designed for attaching SIP-3 conductors to supporting insulating suspensions on intermediate and intermediate-angle poles. The clamp's design includes a pressure plate with piercing elements, allowing installation without removing the conductor's insulation. The absence of a closed magnetic circuit in the design prevents losses due to remagnetization.

There are modifications of the clamp:

• PG-30/12-20 SIP-A: equipped with a U-shaped bolt for connecting the UZD-4 shunt.
• PG-30/12-20 SIP-K: includes a special connector for installing a rod used for operational short-circuiting and grounding during maintenance work on overhead lines.

The products are manufactured according to technical specifications TU 3449-001-52819896-2017.
