Conso Electrical Science and Technology Co., Ltd. aims to produce a 30kva 30 kva dry type step down transformer in a outstanding efficiency and low energy consume. From the year of the established, Conso Electrical has expertise in developing the production management system to assemble ONAN transformers and cast resin transformers. The company has enhance the “4S+3E” management system to standardize production process and execute in excellence. We're eagerly seeking collaboration opportunities on a global scale.
The 30kva 30 kva dry type step down transformers can prevent the risk of transformer oil fires and explosions resulting from faults that may occur during operation. Since the insulation materials in dry-type transformers are all flame-resistant, even if a fault occurs during operation, leading to a fire or an external ignition source, it will not escalate the severity of the fire.
The 30kva 30 kva dry type step down transformers do not have issues such as oil leakage, common in oil-immersed transformers, and do not suffer from problems related to transformer oil aging. Typically, the maintenance and repair work for dry-type electrical transformers is significantly reduced, and in some cases, maintenance can be entirely avoided.
The 30kva 30 kva dry type step down transformers are usually designed for indoor installation but can also be adapted for outdoor use in specialized applications. They can be installed in the same indoor space as switchgear, reducing the installation footprint.
The 30kva 30 kva dry type step down transformers, being oil-free, have fewer associated components. They lack features such as oil storage tanks, safety ducts, and numerous valves, and do not encounter sealing issues.

To ensure the normal operation of the transformer, regular inspections and maintenance are necessary. In dry and clean environments, an annual inspection is recommended, while in locations prone to dust or chemical smoke pollution, inspections should be conducted every 3-6 months. The inspection items are as follows:
(1) Check for dust accumulation and rust in various parts of the dry-type transformer.
(2) Verify the accuracy of temperature control and temperature display values, and record the highest temperature ever recorded.
(3) Inspect joints and conductive parts for signs of overheating or loosening.
(4) Ensure the reliable operation of the fan cooling system according to the set values.
(5) Examine insulation in all parts for discoloration, delamination, or cracking.
(6) Inspect the grounding system of the dry-type transformer: check for damage or breakage in grounding conductors, loose or damaged connections; perform a point-by-point check of the entire grounding system for robustness and reliability; inspect the transformer and its distribution system.
