CPE Jackets

Southwire Offers CPE Jacket for Power Generation Applications
XLPE/CPE Construction Provides Cost-Effective Alternative for Specifiers
Engineers choosing wire and cable for power generation facilities now have a lower-cost alternative when they specify CPE (chlorinated polyethylene) jacketed cable.  Southwire has developed a line of CPE-jacketed products for 600V power and control cables and for 5-35kV medium voltage cable for power generation facilities. 
This offering is part of Southwire’s broad line of industrial cables for the power generation market and other applications with similar requirements.  On 600V cables, our product utilizes FR-XLPE (flame retardant cross-linked polyethylene) insulation with CPE jacket and offers an approved lower-cost alternative to FREP/CPE (flame resistant EPR –ethylene propylene rubber- with a CPE jacket) or FREP/Hypalon® construction.  FR-XLPE/CPE product carries Type TC ratings required for tray cable applications.
CPE has been a popular cable jacket material in the power generation market since the 1970s.  “We’re seeing CPE (chlorinated polyethylene) jackets displacing CSPE (Hypalon®) in power plant applications,” says Doug Ramsey, Southwire’s vice-president for industrial power cable. “CPE and CSPE are both traditional in this market, but CSPE now seems to be giving way to new CPE formulations. It’s economics meshing with new CPE compounding technology.”

“There are environmental issues, too,” says Ramsey. “Tetrachloride found in CSPE is on the EPA materials list and the environmental and disposal considerations are helping move buyers to CPE.”
CPE’s solid performance when exposed to fire also makes it a preferred alternative to PVC. Most power generation cable specifications allow for either EPR or XLPE insulations with CPE jackets, but exclude PVC jackets.  The FR-XLPE construction is substantially less expensive than FREP, which can make a significant difference in power cable budgets.
Moreover, many cable applications now require an added degree of flame performance over PVC.  For maximum fire safety, Southwire’s low smoke, non halogen SOLONON jacket and insulation compounds offer performance features that are better than CPE, Hypalon® and PVC.  This offering allows cable buyers in the power generation market to receive the high quality products and services from Southwire while retaining their familiar specifications.
