Composite Insulators for Line, Post, Suspension and Bushing Routes
This direct DSE selector compares composite crossarm, horizontal line, pin, post, suspension, wall bushing, transformer bushing, CT-integrated bushing, porcelain bushing and accessory routes by system position and rating boundary.
12 product pathsLine support, suspension, bushing and accessory routes stay on one selector page.
1 Drawing tabOnly the suspension route has a clean English drawing page available.
CollectionPageSchema uses CollectionPage, ItemList, BreadcrumbList and FAQPage.
Updated Jun 30, 2026Technical documents, product images and modal data were reviewed together.
Product paths
Composite insulator paths by system position and interface duty
This category stays as one direct selector page. Each modal keeps line support, suspension, bushing and accessory rating boundaries separate.
CI 01Crossarm
Composite Crossarm Insulator
Composite crossarm insulator path for insulated overhead crossarms where the square core, silicone housing, end fittings and interface load must be confirmed together.
CI 02Horizontal line
33kV Horizontal Line Composite Insulator
33 kV horizontal line composite insulator path for line post or horizontal support duty on overhead feeder structures.
CI 03Pin route
Composite Pin Insulator
Composite pin insulator path for 12-33 kV pin route selection where spindle thread, shed profile and pollution duty decide the final model.
CI 04Post route
Composite Post Insulator
Composite post insulator path for station post or equipment support duty where cantilever and bending duty are more important than suspension tensile rows.
CI 05Suspension
Composite Suspension Insulator
Composite suspension insulator path for overhead line tension and suspension strings where FXB and FXBW rows separate voltage, SML and creepage requirements.
CI 06Wall bushing
Wall Bushing Insulator
Wall bushing insulator parent bushing route for through-wall conductor path selection across dry composite, porcelain and CT-integrated variants.
CI 07Transformer bushing
Dry Resin Impregnated Transformer Bushing
RIP transformer bushing path for transformer tank interface duty where oil side, air side, conductor and flange data must be released as a matched set.
CI 08Dry wall bushing
Dry Resin Impregnated Wall Bushing
FCRG wall bushing path for indoor and outdoor wall interface selection with dry capacitive insulation and silicone-rubber outer sheds.
CI 09Wall bushing with CT
Dry Composite Wall Bushing with Current Transformer
Dry composite wall bushing with current transformer path where the conductor route and CT secondary winding must be confirmed as separate electrical functions.
CI 10Dry porcelain
Dry Porcelain Wall Bushing
Dry porcelain wall bushing path for capacitive main insulation with porcelain coat where porcelain construction must not be mixed with silicone-rubber wall bushing rows.
CI 11Porcelain wall
Porcelain Wall Bushing
CWW wall bushing path for porcelain wall route selection where project conditions decide whether pure porcelain or dry capacitive construction is required.
CI 12Accessories
Composite Insulator Accessories
Composite insulator accessories path for fittings and end hardware selection after the main insulator route is already known.
Page roleDirect DSE category selector for line support, suspension, bushing and accessory routes.
The page stays under /distribution-switching-equipment/composite-insulators/ because the current data supports category-level selection.
Product routes were checked against the Composite Insulators reference set.
Content, modal data, processed images and schema were reviewed together.
Mixed-language scans and Chinese drawing pages stay internal.
Accessory selection stays below the chosen insulator path.
Application fit
Place the insulator before choosing the product route
The first question is not model number. It is where the insulator sits: overhead line support, suspension string, wall pass-through, transformer tank interface or hardware package.
Crossarm, horizontal line, pin and post positions
Use these paths when the conductor support interface and mechanical load decide the route.
FXB and FXBW tensile route
Use this path when SML, end fitting and string duty define the order boundary.
Wall, transformer, dry, porcelain and CT-integrated routes
Use these paths when conductor pass-through, flange and current data are the main constraints.
End hardware after product path selection
Use accessories only after the main insulator family and interface load are known.
Selection matrix
Compare line, post, suspension and bushing routes before RFQ release
Use this matrix to open the right modal first. Do not transfer rating rows across unrelated product paths.
Decision route
Interface duty
What to confirm
Crossarm routeInsulated crossarm support on overhead pole
Core section, end fitting and attached equipment
Confirm bending load, hole pattern and creepage distance
Line-support route33 kV horizontal, pin or post insulator
Conductor support, bracket interface or station support
Confirm voltage, creepage and mechanical support duty
Suspension routeFXB and FXBW suspension insulator family
Tension or suspension string on overhead line
Confirm SML, end fitting, voltage and drawing need
Bushing routeWall, transformer, dry composite, porcelain or CT-integrated bushing
Conductor path through wall, tank or equipment interface
Confirm voltage, current, flange, wall thickness and CT data if used
Accessory routeFittings and end hardware
Hardware selected after main insulator path
Confirm load, hole size, finish and matched insulator family
Working principle
Core rod, silicone housing, end fitting and bushing interface
Composite insulator selection depends on the load path and the insulation path: fiberglass core or capacitive insulation, silicone housing or porcelain coat, metal fitting or flange, and the conductor or support interface.
Core or capacitive insulationLine insulators use a rod/core path; bushings use a conductor-through-insulation path.
Housing and shedsSilicone rubber, porcelain coat and shed profile determine creepage and environmental fit.
End fitting or flangeHardware must match tensile, cantilever, wall, tank or conductor interface duty.
Electrical boundaryVoltage, current, BIL, creepage and CT data stay with the matching product path.
Rating boundary
Keep line-insulator and bushing rating rows separate
The page does not reuse one family’s values for another route. Each modal states what the available documents support and what the RFQ must confirm.
Document review
Review documents for composite insulator selection
Only public-ready English drawing material is exposed. Mixed-language scans, watermarked pages and route-level images are used only to set the selection boundary.
12 clean card images
All product cards use processed images with complete alt, width and height attributes.
Only suspension has Drawing
CI-05 has a processed English Product Drawings page; the other paths remain SPEC-only.
Use listed values carefully
Crossarm and suspension rows are included only where document values were readable.
Selector, not SKU offer
The page uses CollectionPage and ItemList, with no SKU offer markup.
RFQ inputs

FAQ
Composite insulator selection FAQ
Why is Composite Insulators kept as one selector page?
The available data supports a direct category selector across line support, suspension, bushing and accessory routes. Subpages can be added later only where a route has enough stable model data and independent search intent.
Why does only the suspension insulator show a Drawing tab?
The suspension PDF includes a clean English Product Drawings page for FXB and FXBW families. Other drawing candidates are mixed-language pages, scans or not confirmed as clean English release drawings.
Can suspension SML rows be reused for post insulators?
No. Suspension SML rows describe tensile string duty. Post insulator support duty needs cantilever, bending and flange data from the project sheet or matching model row.
What RFQ details should be sent for composite insulators?
Send product path, system voltage, creepage or pollution grade, mechanical duty, fitting or flange route, wall or pole interface, drawing requirement, quantity and destination standard.
Request review
Request a quote with composite insulator details
Send the product path, voltage and current data, mechanical duty, fitting or flange route, drawing need and quantity so XIYA POWER can return the suitable path, drawing check and quotation boundary.
