General description

TIRESCA® offers an ideal solution and makes a protection against small animals needless. The cable connection taps as well as the fitting of the current transformer are easy to carry out.

TIRESCA® contains the same protection tube as fully insulated DURESCA® busbars therefore it can be used for indoor as well as for outdoor services.

The problem of animals and branches penetrating in substations is globally known. That's where MGC provides the right solution with its TIRESCA®program.

Main advantages

The conductor is made of a cylindrical aluminum alloy type EN AW-6101B T7, or of an electrolytic copper E Cu ETP H. The direct attached TIRESCA®insulation consists of a vacuum cast epoxy resin.

On the whole length of the busbar, the insulation is covered with a corrugated polyamide protection tube.

This tube provides an effective barrier against moisture ingress, a good protection against shocks and is UV radiation resistant (tested according to ASTM D 2565).

  • Designed for indoor, indoor-outdoor and outdoor service
  • Highest short-circuit capability
  • All busbars are factory tested
  • Adaptable system for all new and existing switchyard
  • Reduced overall dimensions and small bending radius
  • Easy and fast assembling
  • Maintenance free
