The communication power supply is a key infrastructure component of the entire communication network. However, it accounts for only a small proportion within the overall communications industry. Telecom operators’ procurement of power supply products mainly focuses on annual equipment maintenance and system devices, with maintenance of power equipment usually representing a higher share of the total procurement volume. The annual investment by telecom operators in the construction of power systems is relatively small; only when large-scale upgrades or network expansions are required will operators increase their procurement of power supply equipment.
