In-house design and development of cost-effective cable twister was undertaken at ARIES for back-end instruments of 3.6 m telescope at Devasthal site located in central Himalayan region of Uttarakhand state in India. Cable twister was designed to route the critical cables such as cryo/helium flexible lines, electrical cables, optical fiber cables and network cables, etc. of various back-end instruments on axial and side ports of 3.6 m telescope. Designing a space constrained cable twister passing through only 350 mm diameter central hole available in telescope pier was a challenging task. Design was analyzed with cables at different twister positions for telescope azimuth rotation from 0 to + ∕ − 2 7 0 ∘ . Flexible design, easy routing of cables and quick detachable characteristic of cable twister make it convenient for routing cables of back-end instruments of 3.6 m telescope. The twister was economically manufactured in-house at ARIES mechanical workshop, assembled, installed and tested with 3.6 m telescope. Provision for changing of separator plates having different numbers and sizes of holes makes it versatile for the different types of cables in back-end instruments. This paper presents the economical design, analysis, manufacturing, assembly, installation and testing of cable twister with 3.6 m telescope. [ABSTRACT FROM AUTHOR]
