The TP-SH3111A 9kv Dielectric Resistance Kevlar Safety Harness is a professional personal fall protect equipment (PFPE) designed exclusively for high-voltage electrical work. Developed by Hangzhou Top Lift Industries Co., Ltd., a leader in fall protection solutions, it combines dielectric insulation, high strength, and ergonomic design to safeguard workers in high-risk electrical environments.
9kv dielectric resistance: Tested to withstand 9000 volts of electrical current, effectively insulating workers from high-voltage hazards during power grid maintenance, substation operations, and overhead electrical work.
Insulation material: High-purity Kevlar (aramid fiber) with low electrical conductivity, ensuring no current leakage even in humid environments.
Kevlar belt and ropes: 45 mm wide Kevlar webbing with tensile strength ≥ 5000 pounds, resistant to abrasion, cutting, and high temperatures (operating temperature: -30°C to 120°C).
Metal components: High-strength alloy steel (corrosion-resistant, zinc-plated finish) with a load capacity of 5000 pounds per D-ring, meeting ANSI fall arrest standards.
4 adjustable points: Adjustable shoulder straps, chest strap, and thigh straps to fit workers of different body types (load capacity: 59 - 160 kg / 130 - 353 lbs).
Padded shoulder and waist cushions: Reduce pressure on the body during long working hours, enhancing comfort and reducing fatigue.
Lightweight design (total weight ≤ 3.5 kg): Ensures flexibility and mobility for workers performing overhead or climbing tasks.
Multi-point D-rings: Dorsal D-ring for fall arrest, frontal D-ring for work positioning, and 2 waist D-rings for tool attachment—providing comprehensive safety coverage.
Quick-release buckles: Heavy-duty, corrosion-resistant buckles for easy wearing and removal, even with gloves.
Component | Material Specifications |
Belt/Ropes | Kevlar (aramid fiber), 45 mm width, thickness 3 mm |
Metal D-rings | Alloy steel, zinc-plated, load capacity 5000 pounds |
Buckles | High-impact plastic + stainless steel, quick-release design |
Padding | EVA foam (waterproof, breathable) |
Thread | Flame-retardant polyester thread |
Parameter | Details |
Model Number | TP-SH3111A |
Dielectric Resistance | 9kv (tested at 50 Hz AC for 1 minute without breakdown) |
Load Capacity | 59 - 160 kg (130 - 353 lbs) |
Breaking Strength | ≥ 22.2 kN (per ANSI Z359.11 - 2014 standard) |
Number of Adjustable Points | 4 (shoulder × 2, chest × 1, thigh × 1) |
Weight | ≤ 3.5 kg |
Color | High-visibility orange (custom colors available for bulk orders) |
Primary Certification: ANSI Z359.11 - 2014 (US standard for fall protection harnesses)
Additional Compliance: OSHA (Occupational Safety and Health Administration) requirements, CE certification for European markets.
Electrical Power Industry: High-voltage power grid maintenance, transmission line inspection and repair, electrical substation operations.
Construction Industry: Overhead electrical installation (street lamps, electrical towers), high-rise building electrical work.
Industrial Manufacturing: Factory high-voltage equipment maintenance, power plant operations.
Utility Services: Telecommunication tower electrical work, renewable energy (solar/wind) facility electrical maintenance.
Safety Lanyards: Kevlar or polyester lanyards (shock-absorbing type recommended for fall arrest).
Retractable Lifelines: 9kv dielectric retractable lifelines for extended mobility.
Anchor Points: Dielectric anchor brackets, roof anchors, and beam anchors.
Tool Tethers: Compatible with Kevlar tool tethers to prevent dropped tools in high-altitude work.
For use only in 9kv and below high-voltage environments (do not use in ultra-high voltage scenarios exceeding 9kv).
Not suitable for flame-intensive environments (Kevlar is flame-retardant but not fireproof—avoid direct contact with open flames).
Inspect the harness before each use for signs of wear, damage, or contamination (replace immediately if defects are found).
Individual Packaging: Each harness is packed in a waterproof, durable nylon bag with product manual, certification documents, and inspection checklist.
Bulk Packaging: 50 pieces per carton (carton dimensions: 60 × 40 × 30 cm, gross weight: 180 kg per carton).
Custom Packaging: Branded packaging available for bulk orders (logo printing, custom colors, and product information customization).
Production Lead Time: 7 - 15 days for bulk orders (sample delivery within 3 days).
Trade Terms: Supports FOB, CFR, CIF, CIP, EXW (Incoterms 2020) for global shipping.
Payment Terms: L/C (Letter of Credit), T/T (Telegraphic Transfer), PayPal, Western Union (flexible payment options for international customers).
Shipping Ports: Shanghai, Ningbo, Shenzhen (China) for ocean shipping; major international airports for air freight.
Pre-Sales Service: Product consultation, sample provision, custom design support (e.g., logo printing, special size adjustments).
In-Sales Service: Order tracking, production progress updates, logistics coordination.
After-Sales Service: 1-year warranty against manufacturing defects; free technical support for harness use and maintenance; replacement parts supply (D-rings, buckles, straps) at cost price.
Each harness undergoes a 9kv AC dielectric test (50 Hz, 1 minute) in accordance with ANSI Z359.11 - 2014 standards. The test ensures no current leakage or breakdown, guaranteeing insulation safety for workers.
No. The harness is designed for single fall arrest use. After a fall, the structural integrity may be compromised (even if no visible damage is present). We recommend replacing the harness immediately to ensure safety.
The MOQ for custom colors (e.g., blue, green, yellow) is 1000 pieces. For orders below 1000 pieces, only the standard high-visibility orange is available.
Sample delivery takes 3 - 5 working days (express shipping via DHL, FedEx, or UPS). The sample fee (50.00 USD) is refundable if you place a bulk order of 500 pieces or more.
