Electrical checklist for construction site / Some points before electrical distribution work

 

Check list of Electrical Erection under FSP ADB Scheme.


For erection work 1st we have to erect  Poles which are 4 types i.e 8.5 meter 180kg PCC Pole,9 mtr 400kg PCC Pole,11 Mtr STP,13 Mtr STP.


Before erection we have to get knowledge about GTPS of above pole.

Let's know how to erect Above pcc pole.


As per approved GA Drawing , following procedure to erect poles.

1

8.5 Mtr 180 kg pcc pole pit size

Manual Pit size

0.45x0.45x1.5 mtr

0.303m3

By hydra/Machine of 20inch blade/fermers

0.508 diax1.5mtr

For Volume-3.14x0.254x0.254x1.5-0.303m3

By deduction pole size we have to do concreting of volume 0.288 m3(1:2:4 mix ratio)


2

9 Mtr 400 kg pcc pole pit size

Manual Pit size

0.45x0.45x1.5 mtr

0.303m3

By hydra/Machine of 20inch blade/fermers

0.508 diax1.5mtr

Volume

3.14x0.254x0.254x1.5mtr

By deduction pole size we have to do concreting of volume(1:2:4 mix ratio)


3

11 Meter STP

Manual Pit size

0.55x55x1.8mtr

By hydra/Machine of 22inch blade/fermers

0.55 diax1.8 mtr

Muffing

300mm

By deduction pole size we have to do concreting of volume 0.44 m3(1:2:4 mix ratio)

4

13 Meter STP

Manual Pit size

0.62x0.62x2.165

By hydra/Machine of 24inch blade/fermers

0.61x2.615mtr

Muffing

300 mm

By deduction pole size we have to do concreting of volume 0.64 m3(1:2:4 mix ratio)

5

Stay Grounting details

Stay distance from pole

6150 Tan θ

(θ angle between pole and stay wire vary from 30 degree to 45 degree)

Stay distance from pole

               For θ=30degree,stay distance from pole should be 3548.55 mm

                       θ=45degree,stay distance pole should be 6150mm

 




Conclusion: I will update here regularly. Please keep visiting regular site I am sharing this knowledge for your ease of work.

concrete pole specification | how to calculate cement, sand and aggregate quantity in concrete

Today I will tell, how PCC pole concreting is done? Before knowing about our topic, let's take a little knowledge about PCC Polls.full form of pcc pole is Plain  Cement Concrete pole .There are various types of PCC Pole like 8 mtr 8.5 mtr ,9 mtr .but Now I will discuss about only 8.5 mtr pcc pole. As per Guaranteed Technical Perticulars(GTP) Total Length-8.5 mtr Pit depth-1.5 mtr Working load applied 300 mm from top-180 kg Weight of the pole-415 Kg. Top dimension-90mmx145 mm Bottom dimensions-90mm x 300 mm we have to maintain pit length is 1.5 mtr and pole should be inside pit is L/6 where L is length of the pole. Explained : L=8.5 mtr Pit depth=L/6+0.075(Base plate) Pit diameter =20 inch(0.508 mtr) Let's go to our topic now. How to calculate cement, sand and aggregate quantities for ratio 1:2:4 Pit Size For one cmt cement required -6 bag Our pit volume (dia-0.508 mtr where r-0.254, depth-1.5 mtr) Volume -pie*r2*h                =3.14*0.254*0...

what are the possible causes of cable faults?

नमस्कार मित्रों,आज मैने HT AB CAble फॉल्ट कियुं होता है उसिके बारे में चर्चा करूंगा।    आप सभी जानते है कि एचटी एबीसी साइट इंजीनियर के लिए सरदर्दी बन जाती है। जैसे ही लाइन चार्ज करते है कुछ मिनटों या महीनों के बाद फॉल्ट आना पैदा करदेता है।   बहुत सारे इंजीनियर तो बोलना शुरू कर देते है कि खराब इनसुलेशन की बजहा से ऐसे फॉल्ट होता है।  बहुत सारे रिसर्च और अनुभव के बाद  बाद में यही नतीजे में पहुंचा कि जो इस्प्रकर की। 1) अन लोडिंग,स्टोरेज और हैंडलिंग सही से होना चाहिए। 2) टर्मिनेशन किट या ज्वाइंटिंग सही से होना चाहिए। 3) एआर्थिंग सही से होनी चाहिए जैसे कि टर्मिनल की latches  एआर्थिग  जरूर करना होता है। एक चीज ध्यान देना कि मैसेंजर तार को भी दोनों साइड में एर्थिंग करने की। ऐसे तो मैने ए भी कहूंगा कि  हर एक खंबे में मैसेंजर तार को एर्थिग करना चाहिए। Please Subscribe my YouTube channel ⁸ साइट पर केबल ड्रम की अन-लोडिंग, स्टोरेज और हैंडलिंग के लिए दिशानिर्देश जो इस प्रकार की होनी चाहिए।  केबल ड्रम की अनलोडिंग या तो क्रेन द्वारा या होइस्ट द्वारा या ट्रक ...
