Tencom Limited was contracted by an Electrical Utility company to fabricate fiberglass poles known as “hot line sticks” for their workers. These sticks are used on high voltage electrical power lines in different capacities. It is important that these poles do not conduct electricity, so as to protect the worker from shock and also to avoid damaging the power lines. This is a specialized process that only a couple of manufacturers in the country have the ability to produce this product. The pole was composed of vinylester resin and special electrical glass. This custom profile was formulated and pultruded using our proprietary techniques, holding tolerances of ±0.030” on the diameter.

The high voltage hot stick is available in lengths of 3’ to 20’, with thicknesses of 1”, 1-1/4”, and 1-1/2” in diameter. Built to withstand 1000 kV per foot, it is durable as well as impervious to moisture. Colored yellow according to customer specifications. Tested to meet the ASTM F-711 standard. Turnaround time for this project was 4 -5 weeks. For more information about this project or our other capabilities please see the table below or contact us directly.
