Durable outdoor isolator switch for Reliable Isolation
Our outdoor isolator switch is engineered to provide safe and visible isolation of high-voltage circuits in outdoor power distribution systems. Designed for substations, overhead lines, and transformer areas, it ensures high mechanical strength, minimal maintenance, and reliable operation even under extreme environmental conditions. The unit features corrosion-resistant metal components, secure manual operating mechanisms, and compact design that fits seamlessly into both retrofit and new installations.
Frequently Asked Questions
What is the primary function of an outdoor isolator switch?
It isolates electrical equipment from live parts, enabling safe maintenance. Typically used in substations and distribution networks, it provides visible and secure circuit disconnection.
Is it designed for load breaking?
No. Disconnect switches should only be operated when circuits are de-energized. For switching under load, consider load break switches or circuit breakers.
What voltage levels are supported?
Weisho disconnect switches cover voltage ranges from 10kV to 36kV, ideal for medium voltage distribution systems.
What mounting methods are available?
We support both pole-mounted and structure-mounted configurations. The choice depends on whether the installation is on overhead lines or substation structures.
How weatherproof is the unit?
Fully weatherproof and corrosion-resistant, our switches are designed for operation between -40°C to +55°C and perform reliably in high-humidity and coastal areas.
Can the switch be manually operated?
Yes. Manual operation is standard, and the switch includes safety interlocks to prevent incorrect handling during maintenance.
What’s the maintenance requirement?
The switch is designed to be maintenance-free for long periods. However, we recommend inspections every 6–12 months to ensure mechanical integrity.
Does it meet international standards?
Yes. Weisho outdoor isolator switches are compliant with IEC 62271-102 and related global standards. Certificates are available upon request.
