Our products include a complete range of high strength “I” section prestressed concrete power poles, pole base blocks (donuts), breast and heel blocks, stay blocks and a complete range of transformer and switchgear pads for all types available in New Zealand. BUSCK provides technical support and training to all customers within the electricity infrastructure industry. Busck provides a number of transport options, both within New Zealand and internationally.
Prestressed Concrete Poles
Busck first started manufacturing concrete power poles over 40 years ago. In 1999 Busck updated our pole designs to meet the then draft standard AS/NZS4065.
Our current pole sizes range from 7.5m up to 18.5m long. All poles are fitted with equipotential bonding points, which meet the requirements of the EEA’s guide for working on de-energised lines. Busck poles can be supplied with or without the added safety option of paint and reflectors before leaving the factory. Busck poles are prefitted with six digit uniquely numbered asset id.
All Busck poles are manufactured to AS/NZS 4065, AS/NZS7000 and are tested to AS/NZS 4676.
Busck pole ratings are based on ultimate limit state strength across line and most have an along line rating of at least 30% of the across line rating. This feature exceeds that required in AS/NZS4065 and along with the poles flexibility, assist to limit cascade failure. All rates are ultimate limit state. Busck poles are used at voltages from 230V up to 110kV lines across New Zealand, from the winterless north to heavy snow and frost areas of the South.
Electricity Associated Concrete Products
To complement the pole range, Busck also manufactures a wide range of precast concrete products associated with the electricity supply industry. These include pole base blocks (donuts), breast and heel blocks, switch handle earth pads, and stay blocks.
Busck manufacture a complete range of transformer and switchgear pads for all New Zealand transformer and switchgear suppliers. Included in Busck’s range are switchgear foundations designed to meet New Zealand seismic requirements.
Busck also manufacture customized products to meet our customer’s needs.
