Guelph Utility Pole Company Limited

Description

Wood utility poles, even those treated with earlier, less efficient CCA formulations, have been used successfully by telephone and power companies for over 45 years. CCA poles put in service in 1940 show no decay related failures in tests conducted thirty-five years later. Poles properly treated with the newer oxide formulations of CCA are expected, based on on-going field and service tests, to last forty years and more. The proven ability of K-33 type CCA-C treated poles to provide decades of reliable service gives them a major economic advantage.

Wood utility poles treated with formulations of chromated copper arsenate (CCA) have been used successfully by telephone and power companies for more than 50 years. Tests conducted on CCA poles put in service in 1940 showed no decay-related failures 35 years later. On-going field and service tests indicate that poles properly treated with today's improved oxide formulations of CCA can be expected to last 40 years and more.

Carbowax ® PEG, was introduced as an additive in Timber Specialties K-33 ® CCA-C pressure treating in 1986, to overcome the increased hardness associated with CCA treated wood poles. Carbowax ® PEG is manufactured by Union Carbide Corporation, the largest producer of PEG in the world. Because PEG is wholly organic, greaseless, tasteless, odourless, biodegradable and low in both environmental impact and toxicity, it is used widely in its various forms in pharmaceuticals, cosmetics, agricultural products and many industrial applications.
