NXAirS armoured MV switchboard

NXAirS armoured MV switchboard / NXAirS型

Overview : With the upsizing of ships, the power system capacity is increasing, and the traditional low-voltage power supply mode can no longer meet the requirements, which is highlighted in the following aspects: large power system loss, large cable consumption and difficulty in laying; The short circuit current of the system is large and the selection of circuit breaker is difficult. The medium voltage power supply scheme can solve the above problems. NXAirS Marine armored medium-voltage switchboard is suitable for medium-voltage power systems of Marine engineering vessels, petroleum platforms and other vessels with rated voltage from 3 to 11kV, main-bus current from 4000A and rated frequency of 50Hz or 60Hz, providing comprehensive control and protection for generators, motors, transformers and cables. With online remote intelligent control, detection and diagnosis of switchboard operation and health conditions, the products meet the classification society, LR, DNV, GL, ABS, BV, NK and other Chinese and foreign classification society specifications.
Features :

Fully meet the latest standard requirements of GB3906-2006, IEC62271-200 and DL/T 404-2007 (insulation) GB/T 11022-2011, IEC62271-1-2007 and DL/T 593-2006, and pass the full set of type tests

Modular switch cabinet structure, advanced technical parameters, highlight the high cost performance products

Standardized and humanized design makes the product easy to operate and maintain, and ensures the personal safety of operators to the greatest extent

Comprehensive solutions and flexible installation methods can meet the needs of different customers in various industries

Excellent Siemens quality management to ensure high reliability of product quality; Experience of users in different industries all over the world
