SPSA

 MV Valve Type Surge Arresters  15kV – 36kV MV / HV Networks

Design Features: The SPSA cover is designed as a universal device for covering up the upper metal hardware and fittings of most types of MV Polymer and Ceramic Surge Arresters available on the market (Fig. 5) . Its inner diameter allows it to house sheds of up to 120mm diameter. In addition to its main intended purpose, this device, given its adaptability and dimensions, can also be used in the following applications:

  •  Its design and inner capacity (Figs. 1 & 2)  allow it to cover up the upper hardware of some types of Post Insulators and Substation Busbar Support Insulators (Fig.5b).

  •  Its cones (Fig. 3) are of sufficient diameter to house busbars of up to 34mm diameter.

 

  •  The SPSA can be optionally used to cover up distribution Transformer Bushings.
  • The silicone thickness used is >3.5 mm, conferring the device the necessary dielectric strength (<36kV) and ensuring its enduring effective performance.

Installation: Its clamshell opening design, with 2 locking points by means of pins, (preinstalled on each device), allows easy installation by hand with no tools on existing lines (Fig.4).
