Voltage Transformers for Paraller Circuits
Parallel transformers are designed to be connected to a normal line voltage (for example, 230VAC). They are typically used in heliports and helipads. Transformers are manufactured to supply a certain voltage on the secondary side. Normally, the voltages are received from standard 6.6 A bulbs or from 12 V bulbs. Possible connection methods involve using one core cable (KRV-type) or two core cable (KRVS-type). The standard primary voltage is 230 VAC, the max current rating 20 A and the frequency 50/60 Hz.
KRV transformers have two primary leads, of 0.6 m, in a T-type connector which has a FAA interface L-823, a style 2 Plug, and the other end with a FAA823, style 9 receptacle.
The secondary lead is 1.2 m in length, cable type 2 x 2.5 mm2, 0.6kV with a receptacle FAA L823, style 7.
KRV transformers are installed using Efla’s standard KD510 series connector kits (page 5) or prefabricated unscreened leads and extension cords (page 7). End Caps (KDCVO1) are used at the end of the circuit.
KRV transformers are installed using Efla’s standard KD501 and KD502 series connector kits (page 5) or prefabricated secondary leads and extension cords (page 6). End Cap (KDVS.END) is used at the end of the circuit.
KRVS uses a standard FAA secondary connector for both incoming and outgoing interfaces. The primary lead length is 0.6 m and it has a style 1 connector. The secondary lead length is 1.2 m and it is equipped with a FAA L-823 style 7 connector. Each transformer can be connected using a prefabricated distribution connector assembly, KDCV.P2R.
