ES4W4W

Overview

The Burndy ES4W4W is a pre-insulated service entrance compression sleeve designed for connecting insulated combinations of copper, aluminum, and ACSR conductors. It features an aluminum barrel with nylon insulation and a polythene cap. The component measures 2-3/4 inches in overall length and utilizes a blue color code on both sides. It supports wire sizes ranging from 6 to 5/4 AWG and is RoHS compliant.

Feature Summary

• Pre-insulated design with nylon jacket and polythene cap for immediate weather protection
• Aluminum barrel construction suitable for mixed conductor materials including copper and aluminum
• Compression connection method ensuring secure mechanical and electrical joints

Applications

• Service entrance connections for insulated conductors
• Overhead distribution line splicing
• Combining insulated copper, aluminum, and ACSR wires

Procurement Notes

Verify the specific application requirements against the official datasheet before purchase. Confirm that the conductor types and sizes match the component's rated capacity. Ensure compliance with local electrical codes and standards such as RUS acceptance where applicable. Check for RoHS compliance if required by project specifications.

Selection Notes

Select this component when joining insulated conductors of varying materials like copper and aluminum in service entrance applications. The pre-insulated nature eliminates the need for separate insulating tape or heat shrink. Consider the blue color coding for identification purposes during installation. Ensure proper crimping tools are available for the specified compression method.
