Encapsulating Resin There are two types of transformers manufactured. The wound primary (type J3FM & J3RQ) and cable or busbar, with different window size (types J4R4-1 & J4R4-2). From an insulation point of view, there are two types of transformers: - Resin moulded in a plastic case, type J3FM and J4R4-1 - Resin moulded, type J4R4-2 and J3RQ.
In both cases, the use of suitably-processed class F epoxy resin provides these CT with a very high mechanical and insulating features. From the primary point of view, two types of transformers are manufactured: - Wound primary, types J3FM and J3RQ - Busbar (with different window size), types J4R4-1 and J4R4-2.
Thus, they are built to meet the most demanding requirements in terms of accuracy and reliability. These transformers are designed for indoor service.
Encapsulating Plastic There are two types of transformers manufactured. The wound primary (type J3XBP) and cable or busbar, with different window size (types J3X & J4X).
They are built to meet the most demanding requirements in terms of accuracy, insulation and reliability. These transformers are designed for indoor service. The case is made with a high-thermal resistance (class F), non-flammable and self-extinguishing plastic material.
From the primary point of view, two type of transformers are manufactured: - Wound primary, type J3XBP - Cable or busbar (with different window size), types J3X, J4X and J4R4-1p
