This document applies to the technical requirements for the design, testing, supply, installation, and related supporting equipment (sensors, controllers, cables, etc.) of automatic reclosing on 11kV columns in Bangladesh Rural Electrification Board (BREB) 11kV 50Hz medium voltage distribution network.
ROCKWILL 11kV Automatic Circuit Recloser is three-phase pole-mounted vacuum recloser designed to comply with BREB 11kV Automatic Circuit Reclose Specification Submission Sheet for Bangladesh rural overhead distribution network. Nominal system voltage 11kV, highest equipment rated voltage 12kV, rated continuous current 630A / optional 1250A, rated short-circuit breaking current 16kA,20kA for 3 seconds. Vacuum interrupter with solid dielectric insulation, SF₆-free. Intelligent protection controller supports up to four programmable auto-reclose operations and lockout on permanent faults. Control cabinet is IP65 tropicalised design to withstand high humidity, heavy monsoon rain and coastal salt mist. Local manual operation and standard SCADA communication protocols are supported. Full IEC type test reports can be supplied and BREB witness test is available upon request. All technical data, drawings and test certificates can be prepared in BREB submission sheet format for tender evaluation and site acceptance.
Outdoor Recloser/Reclosure China Supplier – provides Single-phase Recloser OEM/ODM China, Triple Single-phase Recloser China Manufacturer, and Vacuum Recloser/Reclosure For Sale options.
25.8kV-38kV Outdoor Auto Circuit Vacuum Distribution Recloser. Direct manufacturer supply for IEC/IEEE compliant distribution automation and feeder protection solutions.
Customizable 15kV to 20kV Outdoor Vacuum Auto Recloser. IEEE-compliant smart grid feeder protection with rapid fault isolation for stable power.
BREB 11kV Automatic Circuit Reclose Specification Submission Sheet is the official tender technical form issued by Bangladesh Rural Electrification Board. It requires suppliers to complete all technical data, drawing information and test evidence of 11kV pole-mounted vacuum reclosers, used for technical bid evaluation to verify compliance with BREB rural overhead distribution network requirements.
BREB 11kV Automatic Circuit Reclose Specification Submission Sheet defines equipment rated voltage of 12kV for nominal 11kV system. The recloser shall withstand 42kV rms power frequency voltage for 1 minute and 75kV peak lightning impulse voltage (1.2/50μs). The solid dielectric insulation shall remain stable under Bangladesh high humidity and monsoon environment.
BREB 11kV Automatic Circuit Reclose Specification Submission Sheet requires the recloser to support up to four programmable auto-reclose operations and lock out upon permanent fault. This function can automatically restore power for transient faults which frequently occur on rural overhead lines.
BREB 11kV Automatic Circuit Reclose Specification Submission Sheet stipulates the control cabinet shall reach IP65 protection. The whole recloser shall be tropicalised, anti-UV, anti-corrosion and resistant to high humidity, heavy rain and salt mist to adapt to Bangladesh monsoon and coastal regions.
BREB 11kV Automatic Circuit Reclose Specification Submission Sheet requires full IEC type test reports. BREB witness test can be arranged as requested. The vacuum recloser automatically detects and isolates overhead faults, restores power supply for transient faults, reduces manual line patrol workload and improves power supply reliability for rural agricultural and residential consumers.
