138KV underground to overhead transmission structures
MEGATRO provide fabrication and design of 138KV underground to overhead transmission structures for our overseas clients. This type structure has post insulation directly installed on pole body and power current transmitted by power cable underground. Sometimes we fixed surge arrester, current transformer and voltage transformer on pole body by clamp.
This structure was made of hollow pipe, which can be quickly deployed with minimal hardware and labor, factory drilled to customer specifications or modified in the field, if required, using a carbide-tip bit. In general, this type of pole fabricated with mild steel or high strength steel, such as ASTM A36, ASTM A572 GR50, GR65, Q235B, Q345B, S355JO, S355JR, ST37, ST52, BS 50B or other.
Our 138KV underground to overhead transmission structures with some type as follow:
(1) Flange connection
(2) Slip joint
(2) Step type
(3) Stagger type
(4) Others
Pole foundation types have:
(1) Direct embedment
(2) Anchor bolt
(3) Based plate
(4) Vibratory steel caisson
MEGATRO provide Series 138KV underground to overhead transmission structures at a much lower material cost than self supporting towers due to the efficient use of steel guy lines, The guyed lattice masts are normally guyed in three directions equally spaced 120 degrees apart over an anchor radius of typically 2/3 of the tower height or as per client special requirements.
