There’s a growing trend towards choosing LOKV explosion-proof electrical equipment with decreasing power ratings. Some manufacturers have even received orders for LOKV units ranging from 110 to 160KW. Neongo ia, producing LOKV with such lower power ratings increases both the manufacturing costs and difficulties.
When IIA low-voltage explosion-proof motors operate at a frequency of 60Hz, their rated voltage is adjusted to 460V. This transition is easily achieved by domestic moto ʻo e fakamoʻoni fakaʻauha manufacturers from their existing 50Hz products.
