Dow 4202 TR-XLPE Celebrates 25 Years of Success

Since 1983, the global power industry has used enough Dow 4202 tree retardant crosslinkable polyethylene (TR-XLPE) to insulate the equivalent of over three million kilometers of underground (UG) medium voltage (MV) cables. Enough to circle the earth 80 times.

In 2008, Dow Wire & Cable is celebrating the fact that Dow 4202 insulation is helping UG power distribution cable systems withstand the test of time. This insulation has exhibited excellent field experience for UG residential and commercial distribution and feeder applications. Samples pulled out of the ground after many years of service show little deterioration and high reliability - 25 years of proven performance to fulfill utility and consumer needs for a dependable power supply.

Dow Wire & Cable utilizes a proprietary technology for its TR-XLPE insulation that helps reduce degradation such as water treeing in underground (wet) conditions. In fact, since Dow 4202 was introduced in 1983, TR-XLPE has rapidly replaced conventional XLPE to become the predominant MV insulation for primary UG distribution cables in North America. Furthermore, TR-XLPE insulation is gaining wider acceptance as a proven technology for improving system reliability, lowering total cable life-cycle costs by enhancing MV cable life, and allowing simplified cable constructions that handle the most challenging wet or dry environments.
