Product Description

KYN28A-24 indoor AC metal armoured pull-out switch cabinet 

.Overview

KYN28A-24 indoor AC metal armoured pull-out switch cabinet is suitable for three-phase AC 50/60Hz power system, for receiving and distributing power, and for controlling, protecting and testing the circuit. APG epoxy casting and reliable solid insulated bus technology are used in the interior of the product for full insulation design. It has good electric field distribution measures. It is a miniaturized switchgear with advanced technology, stable performance, reasonable structure, convenient use, safety and reliability.
The switchgear meets IEC298, GB3906-91. In addition to be used with domestic VS1 vacuum circuit breaker, it can be used with VD4 from ABB, 3AH5 from Siemens domestic ZN65A, and VB2 from GE, etc. It is truly a power distribution deviece with good performance.
In order to meet the requirement for wall mounting and front-end maintenance, the switchgear is equipped with a special current transformer, so that the operator can maintain and inspect it in front of the cubicle.

Ⅳ.Features

Bus bar adopts thermal shrinkable insulating material or epoxy coated insulation method to optimize the shape of the electrode, make the cabinet structure compact and reduce the occupied area.
2. The cabinet body is made of high-quality cold-bonded steel plate and imported aluminium-zinc coated sheet metal, which are processed by NC sheet metal and connected by high-strength bolts, nuts and rivet nuts.
3. The switchgear equipment has other primary schemes such as cable in-out line, overhead in-out line, bus connection, isolation, voltage transformer, lightning arrester and so on.
4. Insulation boards are installed in bus cabinet, handcart cabinet and cable cabinet, which greatly improves the insulation level.
5. The interlock between main switch, handcart, ground knife switch and cabinet door adopts mandatory mechanical door lock mode to meet the "five-proof" function.
6. Friendly man-machine interface makes switchgear operation programmable and formulaic, and the operator can see it at a glance.
7. The main wiring scheme can reach more than 160 kinds, and has strong structural adaptability, which can meet the needs of different users.
