Dow Electrical & TelecommunicationsEnhanced Performance
MV Cable Insulation
What does DOW ENDURANCE™ HFDC 4202 EC do for utilities?
Life extension
Enhanced reliability / better asset utilization Ease of installation
Optimized costs, consistent installation Significantly Lower (~50%) water tree growth rate
Longevity, lower probability of failures Higher quality cables
Manufacturing consistency MV 105 C Rating for the material
Option for higher ampacity, when needed
How do we create the value?
Critical performance features for enhanced cable life…..
Higher electrical breakdown strength
Minimize electrical risks …water treeing in particular…
Improved / consistent cable installation
Eliminate accessory related risks
Improved cable quality Robust, consistent manufacturing that minimizes insulation related stresses due to fabrication process
Technology of DOW ENDURANCE™ HFDC 4202 EC
Same proven “Tree-retardant” additive technology used in 4202 for nearly 30 years.
Produced in totally integrated, state-of-the art facility − Feedstock to finished compound− Ongoing investments in continuous improvement
Extended cable life(enhanced formulation technology)
Improved ease of installation(reduced insulation shield stripping force)
Enhanced quality cable manufacturing(more robust processing)

Action Steps
We recommend utilities update their MV cable specifications to reflect the acceptance of DOW ENDURANCETM HFDC-4202 EC. Ask your cable manufacturer to provide cables with this insulation material.
Dow welcomes dialog on specific steps to make this happen
Dow also would like to understand your experience with the new compound: Do your line technicians like the lower strip capability? Do they think this makes the installation easier? Does this capability increase the likelihood of higher quality
accessory installation? Are there any issues with cables made from the new compound?
