Personnel engaged in power construction must be equipped with work clothes that meet industry standards, and all clothing must have the three core functions of protection, comfort, and safety. Clothing must be purchased uniformly by the enterprise, and unauthorized modification or use of non-designated products is prohibited to ensure personal safety during the construction process.
Material Selection Requirements
The selection of materials directly determines the protective performance.
The outer fabric must be flame-retardant, pass the vertical combustion test, with continuous combustion time no more than 2 seconds, afterburning time no more than 4 seconds, and damage length no more than 10 centimeters.
The inner layer is made of breathable and sweat-absorbing fabric with a cotton content of not less than 35%.
Double-line wrapping is used at the joints to ensure a tearing strength of over 120 Newtons.
Anti-static fibers should be evenly woven into the fabric, with a surface resistance value controlled between 10^6 and 10^9 ohms.
Structural Design Requirements
The design of clothing structure follows the principle of prioritizing functionality.
Top: Adopts a stand-up collar with a Velcro closure device; double-layer wear-resistant pads (thickness ≥3mm) are installed on the shoulders; the front chest is equipped with two waterproof tool bags with 15-degree angled openings for easy retrieval; a 5cm-wide reflective strip is sewn on the back, with a visible distance of 150 meters at night.
Pants: Straight tube version with detachable knee pads at the knees; elastic cuffs with anti-hook threads are built into the hems.
Safety Standard Requirements
The safety standards strictly comply with national regulations.
Comply with the Class A standard of GB8965.1-2020 "Flame Retardant Protection of Protective Clothing".
Supporting equipment includes insulated gloves (withstand voltage level 10kV), puncture-resistant shoes (puncture resistance 1100N), and safety helmets (impact absorption energy 490 joules).
Winter version is equipped with an integrated 12V low-voltage heating system, covering the back and abdomen, with a temperature control range of 25℃-40℃.
Use and Maintenance System
Establish a complete system for use and maintenance.
Operators should check the integrity of their clothing before starting work every day, focusing on detached reflective strips, damaged fabrics, etc. If the open line exceeds 3cm or the flame-retardant layer wears more than 20% of the area, it must be replaced immediately.
Weekly centralized cleaning and disinfection with water temperature controlled below 40℃, and bleach is prohibited.
Hang in a dedicated wardrobe during storage to avoid contact with oil stains or corrosive substances.
Special Work Scenario Supplementary Regulations
Live working: Requires full-screen protective clothing with a fabric resistance value not exceeding 10 ohms, equipped with a potential transfer rod and conductive shoes.
High-altitude operations: A falling brake connection point is installed, with the load-bearing anchor point set in the middle of the back scapula and a tensile strength of not less than 22 kilonewtons.
Cable well operation: Equipped with an independent breathing device, and a quick release device is installed on the front chest of the clothing, which can be removed within 3 seconds in emergency situations.
Three-level Inspection Process
Entrance inspection: Verify the product testing report, focusing on combustion performance, electrostatic parameters, mechanical strength and other indicators.
Monthly spot checks: Conducted by safety personnel using professional equipment, including retesting of fabric flame retardancy and testing of seam strength.
Annual third-party testing: Submitted to CMA-qualified laboratories, covering 12 major items and 58 minor items.
