Product Description
XHHV515-8L High Voltage Surge Generator

The XHHV515-8L high voltage surge generator fully complies with DL/T846-2016 “General Technical Conditions for High-Voltage Test Equipment” and DL/T474-2017 “Implementation Guidelines for Field Insulation Tests”. Designed for shock discharge during cable fault testing, it also performs DC withstand voltage tests on other electrical equipment. By integrating the DC high-voltage source, energy storage capacitor and discharge ball gap into one portable unit, this generator completely replaces traditional test transformer systems that weigh hundreds of kilograms — making it the ideal field companion for contractors who locate faults on 10kV and below power cables.

Applications & Target Audience: Engineered for electrical engineering contractors, underground power cable construction and emergency repair crews, and on-site cable fault locating service teams that need a portable high-voltage impulse source to clear faults on 10kV and below distribution cables and to verify insulation integrity with DC withstand tests.

Advanced Features
Automatic over-current, over-voltage and over-temperature (65°C) protection for worry-free field operation
Dual functions in one unit: DC withstand voltage testing and impulse discharge for cable fault location
Super short-circuit protection — the high-voltage output can be shorted directly to ground without damage
Dual Class 1.5 pointer meters for current and voltage, showing the discharge process in real time
High-voltage-side voltage measurement for real-time, accurate readings
Zero-start protection with potentiometer zero-output interlock for safe voltage ramp-up
Voltmeter keeps indicating capacitor voltage in the stop state, so crews can confirm full discharge before touching leads
Discharge interval adjustable within the safe range to match site conditions
Ultra-light integrated design (≤25kg) replaces 100kg+ transformer, control box and pulse capacitor sets

For contractors, every minute of outage costs money. The XHHV515-8L arrives on site ready to work: one unit, one operator, no crane, no separate control box — thump the fault, confirm the discharge, and hand the excavation point back to the crew.

One Unit Replaces a Traditional Three-Piece Test System

Traditional DC surge testing requires a 5kVA test transformer (over 60kg), a separate operation box (over 30kg) and a pulse energy storage capacitor (over 20kg) — more than 110kg of equipment that must be transported, wired and coordinated on every job. The XHHV515-8L collapses this system into a single 25kg instrument:

FAQ
Q1: Who is the XHHV515-8L high voltage surge generator designed for?
It is designed for electrical engineering contractors, underground power cable construction and emergency repair crews, and on-site cable fault locating service teams that test 10kV and below distribution cables.
Q2: What output does it provide for cable fault location?
It delivers 0-15kV impulse voltage with 0-900J discharge energy from a built-in 8μF capacitor at 400W impact power, negative polarity output, plus 0-10kV DC withstand voltage output for insulation testing.
Q3: How does it protect the operator on site?
Safety features include over-current protection (8mA, more than 4 seconds), over-temperature protection at 65°C, zero-start interlock, super short-circuit protection, dual display meters, a dedicated discharge rod, and capacitor residual-voltage indication in the stop state.
Q4: How much weight does it save compared with traditional test transformers?
A traditional 5kVA transformer set exceeds 110kg (transformer over 60kg, control box over 30kg, pulse capacitor over 20kg). The XHHV515-8L integrates all functions into one ≤25kg unit that a single technician can carry.
Q5: What packaging, delivery and after-sales service do you provide?
Each unit ships in a wooden case with all accessories (power cable, HV output line, ground wires, discharge rod and fuses). Delivery takes 5-8 working days, with one-year free warranty and lifetime maintenance and technical service.

O equipamento XHHV535-2L teve um desempenho excepcional nas mãos da nossa equipe de manutenção de energia. Localizamos uma falha em um cabo subterrâneo na zona rural do interior de São Paulo. Ele manteve medições precisas mesmo em ambientes com alta temperatura e poeira, sua construção robusta o torna adequado para trabalhos de campo e reduziu significativamente o tempo de reparo. Recomendamos fortemente o equipamento para todas as equipes de manutenção.

جهاز اختبار الكابلات XHHV535‑4TS أداؤه ممتاز لفريق الصيانة الحكومي لدينا. استخدمناه لفحص عطل كابلات أرضية في محطة محولات شبرا الخيمة بالقاهرة. يعمل بدقة عالية حتى في درجات الحرارة المرتفعة، جهاز متان للعمل الميداني، يوفر لنا الكثير من وقت الإصلاح. نوصي به بشدة لفرق الكهرباء.

We tested the XHHV535-4Z on several underground cable repair jobs in Houston. It helped our team locate faults faster and reduced unnecessary excavation. The equipment is powerful, stable, and easy to operate in the field. A great solution for utility and industrial cable maintenance.
