Dow Endurance DHDA-7708 BK
About this Product
DOW ENDURANCE DHDA-7708 BK is a thermoplastic semiconductive compound specifically designed for jacketing over medium, high, and extra-high voltage power cables. It combines the excellent physical properties and low moisture vapor transmission normally associated with Dow insulating jacket materials with the conductivity of thermoplastic semiconductive insulation shielding compounds. In medium voltage cable applications, a semiconductive jacket provides cable endurance and prolongs cable life by reducing neutral-to-ground impulse voltage. The semiconductive jacket enables on-reel cable diagnostic analysis in high and extra-high voltage applications.
Compared to conventional thermoplastic semiconductive materials, DOW ENDURANCE DHDA-7708 BK offers:
Improved environmental stress-crack resistance
Improved low-temperature properties
Improved thermomechanical properties
Reduced adhesion to strippable insulation shields
Improved cut-through and abrasion resistance
Reduced moisture vapor transmission
Details are shown in Figures 1 to 4
