Understanding the composite tension insulator SDI90.280
The composite tension insulator SDI90.280 is designed to withstand mechanical tension loads while providing excellent electrical insulation in power systems. The SDI90.280 is recognized for its ability to handle moderate to high tension requirements in medium-voltage (MV).
There are many tension insulator supplier on the market, Jera Line is a leading manufacturer based in China, producing a full range of products with competitive price for low-voltage and medium-voltage applications, there is a HDPE tension insulator PPI-1-150-55 which can be the analog of composite tension insulator SDI90.280.

Key Features of JERA LINE's PPI-1-150-50 HDPE tension insulator
HDPE light weight insulator is a kind of electrical insulator product applied to an overhead power distribution line to fix the conductor to its supporting phase conductor hardware.
The pin insulator can be used with a wide range of cables including aluminum conductor steel reinforced (ACSR) cable, aluminum and copper bare wire. The new lighter weight insulators provided longer leakage distances, were compatible with all conductor types and were UV and track resistant.
Jera Line is a comprehensive company combining both factory and trading operations. Specializing in low-voltage and medium-voltage cable infrastructures for over ten years, Jera Line has gained excellent feedback from customers, to choose us as your supplier due to the following reasons:
Short - circuit overcurrent test to ensure the product safety, Mechanical strength test and Temperature & humidity aging tests, to check the durability when exposed to high/low temperatures and humid surroundings.

The analog of composite tension insulator SDI90.280 is widely recognized for its role in securing and tensioning medium voltage covered conductors in overhead line construction.
By choosing Jera Line’s MV PPI-1-150-50 HDPE tension insulator as an alternative to SDI90.280, network operators gain a cost-effective, factory-direct solution that meets international standards and guarantees dependable performance for rural, urban, and industrial MV distribution networks.
