Insulating Stool for Substations
Delivery: made-to-order items, 3–7 working days; lead time for large quantities is confirmed with the quotation.
Warranty: per manufacturer.
Insulating stools are placed in transformer substations and electrical rooms so the operator stands isolated from earth when switching medium-voltage equipment. Prices from 3,840,000 VND each, excl. 8% VAT.

Indicative prices, excluding 8% VAT, delivered in Ho Chi Minh City; exact prices depend on quantity and stock at the time of quotation. Export processing enterprises (EPE): VAT 0% invoice, and PRIMEAG handles the on-the-spot import/export customs declaration for orders from 20,000,000 VND.
Construction
- Top: fibreglass composite with anti-slip ribs, bearing a standing person and tools.
- Legs: 4 porcelain insulator posts (traditional type) or hollow composite posts (light, unbreakable); feet with rubber pads.
- Voltage class: 10–15 kV for distribution substations, 24 kV for 22 kV networks, 35 kV for intermediate substations.
Use and storage
- Place on a flat, dry floor in front of the equipment to be operated; stand fully on the top and do not let your feet touch the floor or metal structures.
- Wipe dust and moisture off the posts and top before use; damp dust on porcelain reduces insulation.
- Discard if porcelain posts are cracked or chipped, composite is cracked or delaminated, or the top is warped.
- Test electrically at the same time as the substation’s mats, gloves and boots; keep the test reports.
Matching equipment for substations: insulating rubber mat, insulating gloves, insulating boots, insulating hot stick, portable earthing set. Guide to choosing by voltage class: electrical safety equipment for electrical rooms and MSB (main switchboard) panels.
FAQ
– How does an insulating stool differ from an insulating rubber mat? — Both isolate the worker from earth. The stool is used in substations and electrical rooms with damp floors or when work at a moderate height is needed; the mat is laid on the floor in front of panels and is more widely used and cheaper.
– What is the difference between composite and porcelain legs? — Porcelain legs are traditional, heavy and break easily on impact; composite is light, unbreakable and moisture-resistant, so it is now more widely used. At the same voltage class, the insulating performance is equivalent.
– What is the delivery time? — Stools are made to order, 3–7 working days; lead time for large quantities is confirmed with the quotation.
Price: from 3,840,000 VND each (excl. 8% VAT).
