GRC  Compact Transformer Substation:

Glass Fiber Reinforced Cement ( GRC )

G.R.C   is a composite material which presents, for electrical transformer substation, similar advantages as the ordinary concrete cement, with the particularly to have  a large  weight reduction.

Among  GRC's typical advantages it is important to note   :

• Excellent mechanical resistance

• Anticorrosion performance

• Greater efficiency against condensation

• Real adoption to all type of environment ( high hygrometrical or intensive sun exposure areas )

• Undeniable sound properties

• Extended product life.

• Well finished aesthetic.

Technical  data for  GRC :

• Resistance to compression                    :    60 - 100  N/mm²

• Young's Modulus                                    :    15 - 25  kN/mm2

• Resistance to lzod shock                        :    15 - 30  N/mm2

• Maximum resistance to traction            :    10 - 17  N/mm2

• Elastic limit effective to traction            :    7 - 9  N/mm2

• Elastic limit effective of flexion               :     10 - 16 N/mm2

• Leghtening of rupture                              :    0.7 - 1.3 %

• Resistance interlaminar to cutting          :     2 - 3 N/mm2

• Resistance to cutting in plane                 :    8 - 11 N/mm2

• Resistance to cutting per perforation      :     30 - 35 N/mm2

• Specific weight                                          :     2 -2.2 m3

• Poisson's coefficient                                 :      0.20 - 0.25

• Maximum resistance to flexion              :    28 - 42 M/mm2

Comparison of compression :

   *  GRC    :    381 Bars,   other traditional concrete    :    67.5 Bars
