Power system for transmission line towers
Specifically designed for on-line monitoring devices of transmission lines, it can be directly installed on the tower to provide stable and maintenance-free power for various monitoring equipment.
- Adopt lightweight design:The weight of the whole machine is ≤30kg. It supports two types of tower installation methods, namely hoop - type and bracket - type, and can be adapted to tower bodies with a diameter of 100 - 300mm.
- Solid and stable:The shell is made of 304 stainless steel, which can withstand harsh outdoor environments such as heavy rain, strong winds (wind resistance level ≤ 12), high temperatures (-40℃ to +80℃), and high humidity (relative humidity ≤ 95%, no condensation).
- Efficient conversion:Equipped with a high-efficiency MPPT photovoltaic controller (conversion efficiency ≥ 98%), it can be adapted to 40W - 90W photovoltaic modules, and can track the power generation power of the photovoltaic panels to the greatest extent. It has a built-in large-capacity lithium iron phosphate battery (30Ah - 100Ah lithium iron phosphate battery can be optionally configured), with a cycle life of ≥ 2000 times, and supports deep discharge (discharge depth ≥ 80%).
- Waterproof design:Protection level: IP66.
