Design features

What the design is built around

This equipment has multiple advantages

it is equipped with a safe and reliable "five-prevention" interlocking device, which can prevent five types of electrical misoperations; it can flexibly select and configure various vacuum circuit breakers such as ZN63A (VS1) and VD4, as well as V07 vacuum contactor load switches, disconnectors, etc.; the handcart is divided into circuit breaker handcart, voltage transformer handcart, etc. according to purposes, and the handcarts for the same purpose have good interchangeability; heaters can be added to the circuit breaker compartment and cable compartment to avoid condensation and corrosion; the enclosure protection level reaches IP4X, and the protection level is IP2X when the compartment or circuit breaker compartment door is open.

Product Structure

The equipment consists of two parts

the cabinet body and the withdrawable handcart. The cabinet body is made of aluminum-zinc coated steel plate, and is divided into a circuit breaker compartment (handcart compartment), a main busbar compartment, a cable compartment and a relay instrument compartment by metal partitions; all metal structures are reliably grounded, and the main busbar compartment and the circuit breaker compartment are equipped with independent pressure release channels.

We independently design and manufacture the following four major product categories

Buyer questions

FAQ for Type MNS Drawout Distribution Switchgear

What is Type MNS Drawout Distribution Switchgear best used for?
This model is specified at the required capacity and 10 kV / 20 kV / 35 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
How is a switch cabinet matched to a transformer?
The cabinet is selected from the transformer rating, fault level, outgoing circuits and protection scheme. Busbar current, short-circuit withstand, IP rating and cable entry are confirmed on the single-line diagram before production.
Which standards and tests are supplied?
The transformer family is designed to GB 1094.1, GB/T 6451 and IEC 60076. Routine tests include winding resistance, ratio, impedance, no-load loss, load loss, insulation resistance and power-frequency withstand. Type and special tests are available on request.
Can the transformer be customised for 60 Hz or a hot climate?
Yes. Frequency, ambient temperature, altitude, enclosure, corrosion class and terminal arrangement are project inputs. The design is adjusted before production, and the approved datasheet becomes the inspection basis.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
