SO 235 Tension Clamp

Product catalog summary

Overview: The SO 235 Tension Clamp by Ensto is designed for anchoring medium voltage bare or covered conductors. It is notable for its ease of installation, as it does not require the removal of insulation from covered conductors. The clamp features an insulation piercing part that maintains the same potential across the clamp, preventing partial discharges and radio disturbances. This feature also allows for the addition of an arc protection device.

Specifications: The SO 235 is suitable for both bare and covered conductors, including types like ACSR 54/9 Raven, ACSR 85/14 Pigeon, and AAAC 132. It is also compatible with insulated messengers of aerial MV cables such as AHXAMK-WM3. The SO 235.1 variant is specifically for bare conductors like ACSR 34/6 Sparrow. The clamp complies with standards ESI 43-14/Issue 2:1990, SFS 2663 § 10.3, and EN 61284 § 11.5.1.

Live-Line Connectors: The SL 30 and SL 36 connectors are used for live-line branching, with SL 30 for bare conductors and SL 36 for covered conductors. Both are made from corrosion-resistant aluminum with stainless steel bolts. For copper branch conductors, the PSS 830 sleeve is required. Installation can be performed using a live-line stick.

Branching and Earthing: Branching and temporary earthing can be achieved using SL 30 and SL 36 connectors with L-shape PSS 923 or U-shape PSS 924 stirrups, both made from corrosion-resistant aluminum.

Composite Tension Insulator: The SDI 80.7 is a 24 kV insulator suitable for installation on angle and terminal crossarms or hooks. It is lightweight, strong, and features a self-cleaning surface. It has a specified mechanical load of 70 kN and a creepage distance of 650 mm. It is tested and certified to IEC 61109 by SGS FIMKO in Finland.

Technical Data: The document provides detailed technical data, including conductor diameters, tightening torques, and weights for various components like the SO 235, SL 30, SL 36, and PSS 923/924 stirrups.

Tension Clamp SO 235 for Live Line Disconnection Point SO 235 is used for anchoring medium voltage bare or covered conductors. The clamp is very easy to install compared with the other clamps on the market as there is no need to peel off the insulation from covered conductors. The insulation piercing part of the clamp keeps the parts of the clamp at the same potential and prevents partial discharges and radio disturbances. The insulation piercing part also makes it possible to add an arc protection device to the clamp. As SO 235 enables adjusting the conductor tension in the line, it can be used...
