10000V High Voltage Insulated Adjustable Wrench
In electrical maintenance, live-line work, or high-voltage equipment installation, safety is the absolute priority. Our Professional High Voltage Insulated Adjustable Wrenches are engineered to protect electricians during operations in energized environments, making them an essential safety tool for every professional power technician.
This series undergoes a rigorous 10000 Volt (10KV) high-voltage insulation test. The dielectric insulation layer tightly encases the handle to effectively block electric current, offering excellent high-voltage and high-temperature resistance for peace of mind when working near live components.
The wrench body is forged from premium integral alloy steel, ensuring exceptional strength, toughness, and resistance to torsion. Equipped with a precision worm gear (nut), the jaw adjusts smoothly and grips fasteners firmly to prevent slipping. Additionally, the laser-marked scale on the jaw allows for precise and quick size adjustments.

FAQ
Q1: How much voltage can this wrench withstand? Is it safe for live work?
This series is tested at 10000 Volts (10KV). It is designed to protect electricians during work in energized environments. However, please always adhere to your local electrical safety operating regulations during actual use.
Q2: Is the insulation layer sprayed or dipped? Will it fall off?
Our insulation layer is made from high-quality dielectric material bonded tightly to the alloy steel body via a special process. It is thicker and more durable than standard spray coatings and will not crack or peel off under normal use.
Q3: Is the wrench body made of alloy steel? How strong is it?
Yes, the body is forged from premium integral alloy steel, offering high hardness and toughness. Compared to cast products, the forging process creates a denser internal structure, allowing it to withstand greater torque without deforming or breaking.
Q4: Do you support OEM (Private Label) production?
Yes, we support OEM/ODM customization. You can customize your own brand logo (laser marking), the color of the insulated handle, and exclusive packaging designs.
Q5: What is the Minimum Order Quantity (MOQ)?
The MOQ depends on your specific requirements (customization and quantity per size). Please contact our sales team for the best quotation and lead time.
