ENDURANCE™ - Compounds for Cable Systems

Protecting Power Distribution Systems

Generating electrical power requires significant effort and investment, making it essential to protect it effectively. ENDURANCE™ Compounds for Cable Systems, produced by DOW®, offer some of the best protection in the power industry for insulation, semi-conductive, and jacketing materials. These highly-respected solutions help deliver underground power distribution cables that meet or exceed global reliability and durability standards. For nearly 40 years, medium, high, and extra-high voltage cables have benefited from the exceptional properties of ENDURANCE™ compounds.

A Commitment to Excellence

ENDURANCE™ compounds provide cable makers and utilities with exceptional mechanical strength, electrical properties, and ageing stability. By collaborating closely with customers, DOW® aligns its technology and expertise with individual application needs. Intensive testing and validation ensure that every compound meets the specific processing and performance requirements of current and next-generation wire and cable products. This dedication to excellence and innovation was recognised with the prestigious R&D 100 award in 2015.

Super-clean manufacturing, packaging, and logistics practices ensure that cable manufacturers and utilities receive pure, high-performing compounds, offering extra peace of mind.

Medium Voltage

Globally, over 3 million kilometres of 15 kV underground (UG) medium voltage (MV) cables made with DOW ENDURANCE™ MV 4202 tree retardant cross-linked polyethylene (TR-XLPE) insulation are in operation. Testing of these buried cables shows little wear after 25 years, with an expected lifespan of over 40 years. Performance advantages of DOW ENDURANCE™ MV 4202 include:

• Excellent balance of cost and performance with over 25 years of proven effective service

• Improved distribution system reliability and very low life-cycle costs

• Longer cable life, reduced replacement costs, and low dielectric losses

• Simplified cable designs that help optimise system costs

• Clean, dependable, and consistent compounds

• Cable manufacture, installation, operation, and diagnostics similar to conventional XLPE

High Voltage

DOW ENDURANCE™ HV/EHV materials have been used globally for cables ranging from 69 kV to 500 kV for over 10 years. DOW®'s super-clean manufacturing, packaging, and logistics practices ensure years of durable and reliable underground cable function without the fear of contaminants that can lead to cable failure. Underground cables are recognised for their technical advantages and consistent performance, including:

• Up to 30% lower power loss

• Increased protection against external factors such as weather and vandalism

• Lower visual impact, enhancing the value of surrounding areas compared to overhead lines

• Smaller right of way and faster approval for installation applications

• Less emission of electric fields or noise

• Lower short- and long-term maintenance costs than overhead lines
