Abstract

This paper describes a new device to be used in conjunction with splice body pre-stretching tools to improve the current installation process for 110kV splices installed on site. This device will be used in the plastic pre-stretched tube removal process to protect the splice body from damage. The two half-circle design can also make installation easier.

A new tool for optimizing pre-stretched tube removal

This paper describes a new device to be used in conjunction with splice body pre-stretching tools to improve the current installation process for 110kV splices installed on site. This device will be used in the plastic pre-stretched tube removal process to protect the splice body from damage. The two half-circle design can also make installation easier.

The new tool in conjunction with splice body pre-stretch tools

Background

The technology of pre-stretching on site is one of the most popular methods for 110kV splice installation. At present, even though the method is acceptable, there is room for improvement in the installation process. After the pre-stretch process on the 110kV splice body and the cable connecting work are completed, the next step is to remove the pre-stretched tube from splice. Due to large amounts of friction between the splice and the tube surface, the splice body may be damaged or the tube may be cracked by the hydraulic clamp.

Description and Advantages

Using the new tool to remove the plastic tube from the splice body will result in a more convenient and safe process. The detailed installation process is as follows:


1. Assemble the 2 halves of the device on the rear side of the splice body.


2. Assemble the hydraulic clamp onto the splice.
