- Description
- A PFE (Power Feeding Equipment) is designed to supply power to the submerged repeaters on the optical fibre submarine cable systems. The product’s main function is as a DC-DC converter as the input voltage is 40.5 to 57 V dc and it outputs a high DC voltage, such as 3KW. which is used with telecommunication apparatus. The PFE is modular in design, such that a number of 3kW converters are connected in series to achieve the required output power. It is made from electrical machinery components, equipment, and parts. The land-based power feed equipment (PFE) is used to power submarine fibre optic cable repeaters for telecommunications shore stations and during cable laying and repair operations. The power feeding equipment provides the function of supplying a constant DC current stably to the submarine repeaters via the submarine cable. The system voltage is determined by the number of submarine repeaters and the length of the cable, and a higher voltage is required as the distance increases. It works by using single or duplicated power units to convert from a low voltage to the high voltage needed to power the submarine cable. With a control cubicle and cable termination box for interconnecting the power units, the submarine cable, the system earth, and the dedicated station earth. The size and configuration of the PFE depends on the current and voltage requirements of the system (0.5-2.0 amps.) The maximum rated output voltage available is 13,5kV. It is packaged packed with in a cubicle covering shelf made of aluminium.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect – a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a)); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b)). GIR 1 - Has been used to classify this product by the terms of heading 8504 - Electrical transformers, static converters (for example, rectifiers) and inductors GIR 3(b) - Has been used as the DC-DC converter is considered to be the essential character. GIR 5(b) - Has been used to identify the type of packaging - It is packaged Packed with in a cubicle covering shelf made of Aluminium. GIR 6 - Has been used to classify the goods to subheading level 8504 40 - Static converters 8 - Digit Code 850440 95 - Other than accumulator chargers; Other than rectifiers or inverters 10 - Digit Code 85044095 90 - Other than for use in civil aircraft. Also Classified in Accordance with: Section Note 3 to Section XVI Harmonized System Explanatory Notes (HSEN's) (II) (D) to Heading 8504
