Proper inspection and maintenance are essential to ensure the integrity of insulating gloves. OSHA regulations require a thorough visual inspection and a field air test before each use. This involves checking for any cuts, punctures, or embedded foreign objects that could compromise the glove's insulating properties. Additionally, gloves must undergo professional electrical testing at a certified facility every six months while in service. To help with this, we offer durable storage bags and recommend storing gloves in a cool, dry place, away from sunlight and ozone, to extend their lifespan.
Leather protector gloves are a critical part of a lineman's personal protective equipment (PPE). They are worn directly over the rubber insulating gloves to provide essential mechanical protection. While the rubber gloves protect against electrical shock, the leather protectors shield them from physical damage such as cuts, punctures, and abrasions from tools, wires, and other sharp objects. This dual-layer system ensures that the primary insulating layer remains undamaged. We manufacture high-quality, durable leather protector gloves that are designed to fit perfectly over our insulating gloves, providing a complete and secure safety solution.
As a leading manufacturer and exporter, we are committed to producing equipment that meets and exceeds international safety standards. Our insulating gloves and other electrical protective gear are manufactured in compliance with strict regulations such as ASTM D120 and OSHA 1910.137. We take pride in our rigorous quality control and certification processes, which ensure that every product from Ningbo Changshi is safe, reliable, and compliant with the global standards required by utility companies and contractors.

We also offer insulated options that meet international safety standards, providing an essential layer of protection against electrical hazards.
To ensure the longevity and reliability of your ratchet wrench, regular maintenance is crucial:
-
Clean after each use: Wipe down the wrench to remove dirt, grease, and moisture. This prevents corrosion and rust.
-
Lubricate moving parts: Regularly apply a thin film of light machine oil to the ratchet mechanism to ensure smooth operation and prevent rust.
-
Inspect for damage: Before and after each job, check the wrench for any signs of wear, cracks, or damage to the handle or socket.
-
Proper storage: Store your wrench in a dry, cool place to prevent moisture buildup and potential corrosion.
The most critical safety feature is insulation. If you are working near live electrical lines, a wrench with 1,000V rated insulation is a non-negotiable safety requirement. Look for wrenches with a lanyard hole for tethering, which prevents tools from being dropped from heights and causing injury to those below. Additionally, features like an ergonomic handle and a built-in hammer with a smooth strike face are designed to reduce user fatigue and provide a safer, more efficient working experience.
Every lineman's toolkit should be equipped with a core set of reliable hand tools and safety equipment. This includes a quality set of pliers (lineman's pliers, diagonal cutters, pump pliers), a skinning knife for stripping cable, a ratcheting wrench, and various screwdrivers. For safety, essential items include insulated gloves, a hard hat, and a body harness. For complex jobs, power tools like hydraulic cutters and impact wrenches are crucial for efficiency and safety. Ningbo Changshi offers a comprehensive range of these tools, engineered for durability and performance in the most demanding environments.
