Product catalog summary
Overview
The SZ 24 Disconnector by Ensto is designed for medium voltage (MV) overhead lines, offering a cost-effective and practical solution for creating disconnection points in the network. It is particularly suitable for rural areas and branch lines due to its breaking capacity of 12.5 A.

Specifications
The SZ 24 Disconnector is tested and approved according to the latest international standards, including IEC 60694, IEC 60265, and IEC 62271-102. Key rated values include:
  • Voltage: 24 kV
  • Power frequency withstand voltage: 50 kV, 60 kV
  • Lightning withstand voltage: 125 kV, 145 kV
  • Normal current: 400 A
  • Short time withstand current: 10 kA
  • Peak withstand current: 25 kA
  • Mechanical endurance: 1000 operating cycles
  • Leakage distance: Minimum 628 mm
  • Ice breaking capacity: 10 mm


Applications
The SZ 24 Disconnector is ideal for use in:
  • Pole mounted substations and cable terminations, where it is rarely operated but provides a reliable and economical solution.
  • Branch lines, where it simplifies operations during fault situations and reduces recovery time.


Installation and Operation
The SZ 24 is easy to install on existing lines without additional constructions. It is a 1-pole device operated by standard live line tools, such as Ensto's CT48.64, and can be used on both bare and PAS lines.

SZ 24 Disconnector-2

SZ 24 Disconnector is an ideal Solution for MV overhead lines SZ 24 is tested and approved according to the newest international standards. Its breaking capacity is 12.5 A, mostly sufficient for rural areas on branch lines. Disconnection Point on The Network Occasionally a part of the network needs to be disconnected e.g. during repair work, when removing trees leaning on the line or during transformer maintenance. To make the fault recovery time shorter, there is need for several disconnection points in the line. This is very expensive when using the conventional disconnectors. Moreover, disconnection...

SZ 24 Disconnector-3

SZ 24 DISCONNECTOR Pole Mounted Substation and Cable Termination Normally there is need for a disconnector on pole mounted substations or on a cable termination, but it is very seldom operated. The disconnector is typically operated only during maintenance or repair work maybe once in ten years. Therefore a traditional disconnector would be expensive in these applications. Ensto´s SZ 24 disconnector offers reliable and cheap solutions for transformer and cable termination installations. It can be installed on a span with line insulators or together with tension insulator on tension crossarms....
