Refinery by night

Case Study


TE Connectivity (TE) developed an innovative heat shrink termination to support an oil refinery in the Omani desert which couldn’t afford the stoppage of its production.

Beyond Normal Environments

The Raychem heat shrink technology is serving utilities and industries for more than 40 years. Among others it's oil barrier, flame retardant and fire resistant properties made this technology perfectly suitable for extreme environments.

The Challenge

Temperature up to 60°C, high UV level, sand damages and heavy pollution combined together can lead to the premature aging of the oil production equipment. 

An Omani oil company was facing electrical breakdowns due to failures in terminations that were only 2 or 3 years in service.

Raychem heat shrink terminations

"TE demonstrated its strength by providing tailor made heat shrink terminations able to remain efficient for years withstanding a combination of environmental stresses."

The Solution

Together TE's engineer and customer's team, designed a new 33 kV Raychem heat shrink termination with an extra layer of insulation. It allows the increase of the wall thickness of the insulation tube at the bottom end of the terminations, resulting in the significant risk reduction of pin holes.

TE's experts decided to use the Raychem EVA (Ethylene Vinyl Acetate) material to design the heat shrink terminations. This material has the ideal attributes to withstand desert environmental conditions. Indeed it has a high UV radiation redistivity and a very low degree of surface cracking. 

The Results

TE's experts assisted the customer's team from the choice of the material to the technical support during the installation. 

By delivering a tailor-made solution to its customer TE reinforced its position of solution provider. The customer adopted TE's products based on EVA material into its specification and awarded us as a key supplier for 33 kV heat shrink terminations, insulators and surge arresters.
