Company Profile...
COMPANY FORMATION







The company started from humble beginnings in 1969 when Mr José de Castro started manufacturing panels and switchboards for South Wales Electrical as a sub-contractor.
In 1974 the company Jocastro was formed when the owner, Mr José de Castro, started manu-facturing panels, switch-boards and junction boxes for Eskom, the electrical utility in South Africa.
Rotary switches were supplied to all the other manufacturers of panels in the country as well. The switch technology and initial infrastructure was purchased “voetstoots” from Germany.
Rotary Switches was expanded in 2000 and the name changed to Lucy Rotary Switches. The product line of the new company was expanded to include 11kV ring main units.
Jocastro Switch-boards cc, a black empowerment wing of Jocastro (Pty) Ltd was formed in 1995 to comply with Eskom’s BEE policies.
HISTORY AND BACKGROUND
Since
1974 the company has grown from strength to strength. Between 1975 and
the early 1990’s, Jocastro became the biggest manufacturer of Phase 1
relay panels in South Africa with Eskom being the main client.
During the 1980’s Jocastro repeatedly won the Eskom National Contract
for junction boxes, relay panels and AC boards, on a competitive basis
and in effect became the sole supplier of these items to Eskom for a
number of years.
In 1980 the company Rotary Switches was established and formed part of
the emerging Jocastro group of companies. This company manufactured self
wiping rotary switches used in the various panels and junction boxes,
etc.
