Over the years, BOWTHORPE HD Series Linetaps have earned an enviable record for robustness and reliability in New Zealand and overseas.
BOWTHORPE HD Series Line Taps have been used extensively across New Zealand electricity distribution networks since 1952 and are tried and trusted by overhead lines engineers and linesmen nationwide. They have a long-term trouble free record in a wide variety of operating conditions.
They have also proven themselves to provide an inexpensive and lasting solution. They can be quickly and easily installed (and removed) without the need for special tools.
BOWTHORPE HD Series Line Taps are made in New Zealand from a particular grade of brass extrusion also made in New Zealand. Every step of the manufacturing process, including the metallurgy, extrusion, machining, tinning and assembly, is critical to the performance of the product. Exacting quality control procedures are applied throughout to provide assurance that BOWTHORPE HD Series Line Taps conform to specification and can be relied on during installation and in service.
This also allows relatively high torque settings to be specified to provide assurance of correct installation time after time without damaging the conductor. Five sizes cover all conductors from 4 – 120 mm2.
BOWTHORPE HD Line Taps have been type tested for 1,000 hours of heat-cycling, to the latest version of BS 3288.1.
Note: all genuine BOWTHORPE HD Series Line Taps are marked with the name “BOWTHORPE”
