Thimble clevises are interface fittings that attach guy wires, conductors, wire grips, or dead-end bails to eye-type fittings on insulators, eyebolts, and pole eye plates in overhead electrical systems. They provide a smooth internal contour that prevents stress concentration within preformed dead-end loops, distributing forces during tensioning and deadending operations to enhance connection integrity in guying and conductor support systems.
These fittings are constructed from ductile iron with hot dip galvanized coating or aluminum alloy for durability and environmental resistance. Hardware includes a galvanized steel pin and stainless steel cotter key, reducing corrosion potential for long-term performance. A generous wire seat diameter maintains the shape of cables, wire grips, or bails during use, while an integral pulling eye accommodates tensioning hooks, streamlining field installation and adjustment.
A standard assembly comprises a body, steel pin passing through the insulator eye, and humpbacked cotter key for secure fastening. This configuration allows straightforward assembly and disassembly, with the pin and cotter key serving as primary removable components. Thimble clevises work with preformed dead-ends, distribution grips, and overhead dead-ends, supporting conductor sizes up to 0.783 inches in normal and light duty applications.
Specific series like TC-17 accommodate various distribution grips and dead-ends, while PCTF and PCTA series feature 1.5-inch wire seat diameters for normal duty applications. Formed steel variants with galvanized coating offer economical solutions for light duty scenarios where corrosion potential is lower.

Часто задаваемые вопросы (FAQ)
Для чего используется Thimble Clevis?
Вилки-крючья Thimble служат соединительными фитингами интерфейса в подвесных или тупиковых креплениях, применяемыми для присоединения ветровой распорки, проводника, тросовых зажимов или тупиковых скоб к изоляторным крепёжным деталям с ушком, ушастым болтам и ушным пластинам на опоре. Они применяются вместе с распределительными зажимами, надземными тупиковыми зажимами, покрытыми тупиковыми зажимами для проводов диаметром до 0,783 дюйма и формованными тупиковыми зажимами для подвесных или тупиковых изоляторов.
Как конструкция Thimble Clevis обеспечивает надежность и предотвращает концентрацию напряжений?
Втулка имеет гладкий внутренний контур, предотвращающий концентрацию напряжений в петле концевой петли PREFORMED Dead-end. Её достаточный диаметр посадочного места для провода помогает кабелю, проушинам или скобам сохранять форму, а встроенная тяговая петля позволяет использовать крюки при операциях натяжения. Конструкция из прочных материалов, таких как ковкий чугун с горячим цинкованием или алюминиевый сплав, обеспечивает коррозионную стойкость и прочность для устойчивой работы в сложных условиях.
What material and duty options are available?
Bodies are available in ductile iron hot dip galvanized for general use or aluminum alloy for higher corrosion potential areas. Hardware is steel hot dip galvanized with stainless steel cotter pins. Series include TC-17 for various Dead-ends, PCTF and PCTA for normal duty applications with 1 1/2 inch wire seat diameters, and formed steel thimble clevises for light duty, economical options.
How is maintenance and replacement performed?
For removal or replacement of an insulator or during maintenance, only the cotter key and steel pin need to be removed to release the clevis, facilitating efficient and straightforward disassembly with minimal downtime.
Can Thimble Clevises accommodate fiber optic cable applications?
Yes, Thimble Clevises are compatible with Dead-ends for optical cable through the appropriate series, ensuring they meet specialized hardware needs.
