9 Disposal and environmental information

9.1 Overview

This chapter specifies the materials used in the bushing. Comply with local environmental regulations on
disposal of this product, the materials used are specified for this purpose.

9.2 Disposal and recycling

ABB strives to minimize the product's impact on the environment throughout its entire life cycle. Technical
and product development focuses on environmental aspects. The ecocycle approach is striven for, and
consideration is taken to the materials' environmental impact and recycling alternatives. The manufacturing
processes are selected to be as safe for the environment as possible.
Disposal of worn-out equipment
Worn-out equipment must be disposed of in an environmentally sound manner.
Much of the material, or the energy content in the material, can be recycled if it is sorted and cleaned. The
quantity of material that can be recycled varies depending on the technical resources and capabilities in each
country. Non-recyclable components should be sent to an approved environmental waste treatment plant for
destruction or disposal.
DANGER!
Be careful when dissembling the bushing.
There is a large quantity of mechanical energy stored in the bushing from its assembly,
disassembly of the bushing can cause it to break with explosive force.
The bushing has these parts and materials
• The conductor is made of copper or low-alloy aluminum.
• The terminals are made of copper or low-alloy aluminum.
The terminals can be plated with silver, tin, gold or nickel, with a thickness up to 20 μm.
• Transformer oil, refer to IEC 60296, class 2.
• The condenser core is made of paper and 1 % aluminum foil, impregnated with transformer oil.
• The top housing, top end nut, test tap and flexible connection are made of aluminum alloys.
• The flanges are made of aluminum.
• The press ring for the oil-level sight glass is made of plated brass.
The oil-level sight glass is made of glass.
• The insulators are made of quartz-silicate or alumino-silicate based porcelain.
Porcelain
After cleaning, the porcelain can be sent for disposal or used for other purposes, such as for use as
filling material.
Electronics
Electronics equipment should be sent to an approved recycling plant, or sorted into different component
materials for correct processing.
