Distribution Switching Equipment / Surge Arresters
Surge Arresters for Line, Station, Low Voltage and Monitoring Routes
This direct DSE selector compares four arrester paths and five monitoring accessory paths by system position, rating boundary, image status and RFQ inputs.
9 product pathsLine, station, LV, cut-out combination and monitoring accessory routes.

Product paths
Surge arrester types by system position and monitoring role
This category stays as one direct selector page. Each modal keeps its own system role, rating data boundary and RFQ confirmation list.
SA 01Line arrester
Distribution Line Surge Arrester
Line type surge arrester path for overhead distribution feeder protection where the MOV column, polymer housing, bracket and earthing lead must match the feeder insulation duty.
SA 02Station arrester
Station Type Surge Arrester
Station type surge arrester path for substation bay protection where higher insulation coordination, base fitting and station grounding must be checked together.
SA 03LV arrester
Low Voltage Surge Arrester
Low Voltage surge arrester path for service entrance, low-voltage panel or downstream auxiliary protection where pole count and AC/DC system type decide the selected device.
SA 04Cut-out combo
Cut Out Surge Arrester Combination
Combi cut-out and surge arrester path for pole-mounted fuse cutout assemblies where protection and overvoltage clamping are packaged in one feeder branch arrangement.
SA 05Counter family
Surge Arrester Counter and Monitor
Accessory family for arrester discharge counters and online monitors. It supports monitoring function selection and does not define the main arrester residual-voltage rating.
SA 06JCQ monitor
JCQ Surge Arrester Monitor
JCQ monitor path for online leakage-current observation and arrester operation counting across multiple high-voltage classes.
SA 07JS-8 counter
JS-8 Surge Arrester Counter
JS-8 counter path for recording arrester discharge operations on the grounding side below the arrester.
SA 08JSZ-8 indicator
JSZ-8 Surge Arrester Counter with Indicator
JSZ-8 counter with indicator path where the base counter function is combined with visible power or fault indication.
SA 09PV counter
Photovoltaic Surge Arrester Counter
PV arrester counter path for solar station monitoring where the device is installed between surge arrester and earth and the PV station package decides final wiring.
Page roleDirect DSE category selector for four arrester paths and five monitoring accessory paths.
The page stays under /distribution-switching-equipment/surge-arresters/ because the current data supports category-level selection, not forced subpages.
Product routes were checked against the Surge Arresters reference set.
Content, modal data, processed images and schema were reviewed together.
Chinese title-block drawings and mixed scan pages stay internal.
Monitor or counter selection stays separate from arrester voltage and residual-voltage data.
Application fit
Place the surge arrester before choosing the model route
The placement question comes first: overhead feeder, substation bay, LV cabinet, fuse cutout assembly, grounding-side counter or PV station monitor.
Protection role
Surge current must have a controlled path from conductor to earth.
Separate overvoltage clamping duty from monitoring duty before selecting the product modal.
Line, station, LV and cut-out combination paths
Use these rows when the device must clamp overvoltage and discharge surge current.
JCQ, JS-8, JSZ-8 and PV counter paths
Use these rows when the project needs operation count, leakage-current monitoring or visible indication.
Earth lead, base fitting and counter connection
Confirm the grounding path before selecting counter or monitor accessories.
Selection matrix
Compare arrester duty and monitoring role before RFQ release
This matrix tells the engineer which product family to open first. The modal then keeps the data boundary for that route.

Monitoring routeJCQ, JS-8, JSZ-8 or PV counter below arrester

Boundary routeAccessory data does not define arrester duty
Counter function stays separate from arrester protection rating
Confirm main arrester data from project sheet
Working principle
MOV column, housing, counter and earthing path
Use this sequence to separate arrester structure from monitor accessories: the MOV column clamps the surge, the housing and shed profile manage insulation, the disconnector or counter interface sits below the arrester, and the earthing path discharges current safely.
Structure checks
Confirm these elements before releasing a product path or accessory path.
MOV columnMetal-oxide blocks clamp transient overvoltage.
Housing and shed profilePolymer or station housing controls insulation distance.
Disconnector or counter interfaceAccessory boundary sits in the lower grounding path.
Earthing pathSurge current must discharge to the grounding system.
Rating boundary
Keep arrester ratings separate from counter ratings
The page does not reuse accessory data as arrester data. Each route states what the available documents support and what the RFQ must confirm.
Voltage, MCOV, discharge current and creepage stay with the selected arrester path.
Line, station, LV and cut-out combination rows cannot inherit each other’s rating data.
Counter and monitor rows define function, not arrester protection duty.
Use JCQ, JS-8, JSZ-8 and PV rows only after the main arrester route is known.
Document review
Review documents for surge arrester selection
Clean product images are used for route recognition. Scanned pages, Chinese-only drawings and mixed instruction pages remain internal unless they can be processed into usable English or clean drawing views.
Use clean product images
Card images avoid document screenshots and keep the product route visible.
State only what the available documents support
Image-only paths require order-sheet confirmation before voltage or discharge-current release.
Keep this page SPEC-only for now
No product path exposes a Drawing tab until clean English release material is available.
Counter data stays accessory data
JS-8, JSZ-8, JCQ and PV monitor rows do not define the main arrester rating.
Engineering selection
Engineering inputs for surge arrester RFQ review
Send the product route and system position first, then match voltage, discharge duty, housing, mounting and monitoring accessories.
Line, station, LV, cut-out combination, JCQ, JS-8, JSZ-8 or PV counter route.
Clamp surge current for arrester routes or count/monitor for accessory routes.
Do not copy values across unrelated voltage classes or accessory families.
Base, bracket, earth lead, counter position and site conditions decide the final package.

FAQ
Surge arrester selection FAQ
What is a surge arrester in this category?
A surge arrester clamps lightning or switching overvoltage and discharges surge current to earth. This page separates line, station, low-voltage, cut-out combination and monitoring accessory routes.
Is this page a single product page?
No. It is a direct product-family selector under Distribution Switching Equipment. The page keeps nine product paths together because the current data supports category-level selection rather than separate SKU pages.
Why are there no Drawing tabs on this page?
Drawing tabs are shown only where clean English drawing material is available. The reviewed drawing candidates contain Chinese title blocks or labels, so the current release stays SPEC-only.
Can JS-8, JSZ-8 or JCQ data define the arrester rating?
No. These are monitoring accessory paths. Arrester voltage, MCOV, residual-voltage and discharge-current data must come from the selected arrester route and project sheet.
How should an engineer choose between line and station arresters?
Start from system position. Use line arresters for overhead distribution feeder routes and station arresters for substation bay or transformer station insulation coordination.
What should be sent with a surge arrester RFQ?
Send product path, system voltage, MCOV or continuous operating voltage, nominal discharge current, creepage or pollution grade, housing route, bracket or base fitting, counter or monitor requirement, site conditions and quantity.
Request a quote with surge arrester details
