Silicone rubber interphase spacer

Silicone rubber interphase spacer is used as well as metal interphase spacer, which is made of silicone rubber consisting of polymer housing, core and insulator end fittings.

The function of Silicone rubber interphase spacer
With environmental exposure to ice and/or wind, Overhead Transmission and Distribution Lines are susceptible to conductor motion that may result in outages or interruptions on the electrical system due to conductor contact, flashovers, or plant damage.

Inter Phase Spacers were developed to minimize the probability of these occurrences by maintaining conductor separation.

The structure of Inter Phase Spacers
◆ Silicone rubber sheds and sheath injection molded
◆ Fiberglass rod
◆ May be coupled with silicone rubber covered rods to increase length

Although lightweight and flexible, Inter Phase Spacers are designed to meet torsional, bending and compression loads of the application. There are a variety of end fittings options available depending on the conductor clamping requirements with or without armour rod.

The performance benefits of Inter Phase Spacer Insulators are listed below.
• Improves Reliability (minimizes interruptions and outages due to conductor contact, flashovers or plant damage in all types of environments)
• Safety (light weight for handling and installation)
• Service Life (consistent performance over its service life)
• Life Cycle Cost (savings over porcelain insulators)

Silicone rubber interphase spacer is popular in electrical systems similarly to metal interphase spacer.
