Semi-Conductive Single Top Tie
Material: Semi-conductive plastic ties are made from a base of clear PVC with a proprietary black co-extruded outer covering selected for its superior electrical tracking resistance properties. Use of this co-extruded material allows application on higher voltages and/or more stressful electrical environments. This material was selected because of its UV resistance, tensile strength, impact strength, flexural strength and self extinguishing properties.
Voltage Applications: Semi-conductive plastic ties can be applied up to 35kV.
Mechanical: Testing has shown Semi-conductive plastic ties will develop unbalanced and lift-off loads equivalent to, or in excess of, a hand tie over covered conductor.
Insulators: To ensure proper fit and performance, it is recommended that only ANSI C29.5 or C29.7 compliant insulators having nominal neck diameters corresponding to Ø 57.2mm (C Neck), Ø 73.0mm (F Neck) and Ø 101.6mm (K Neck) be used. Semi-conductive plastic ties are suitable for use with either ANSI compliant polymer or porcelain insulators.
Description: Semi-conductive plastic line ties/ top ties are intended for use with covered conductors and vertically-mounted tie top insulators on crossarms or pole-top-mounted insulators. Line angles of up to 15° can be accomodated when used with any plastic covered conductor.
