Silicone Coated Fiberglass Sleeving Supplied to India for Motor Lead Insulation
Case Overview
In 2026, Chengrui received an inquiry from an electrical insulation materials buyer in India. The customer was purchasing insulation materials for local motor repair workshops and electrical equipment users.
The product they needed was silicone coated fiberglass sleeving, also known as silicone resin fiberglass sleeving or 2753 fiberglass sleeving.
The material was mainly required for:
motor lead wire insulation
transformer wiring protection
generator lead protection
electrical cabinet wiring
high-temperature cable protection
The customer was not looking for the cheapest sleeving. Their main concern was whether the product could provide stable insulation performance, clean coating quality and correct inner diameter for daily assembly work.
Why the Customer Needed Silicone Coated Fiberglass Sleeving
The Indian customer's end users worked with motors, small transformers and industrial electrical equipment.
In these applications, wires and leads may be exposed to heat, vibration and mechanical friction. Ordinary plastic sleeving is not always suitable when the wire is close to the motor winding area or other high-temperature parts.
The customer needed a sleeve with better heat resistance and electrical insulation performance.
Silicone coated fiberglass sleeving was suitable because it combines:
braided fiberglass strength
silicone resin surface insulation
Class H heat resistance
good flexibility
self-extinguishing performance
multiple voltage grades
different colors for wire identification
This made it a practical product for local motor repair and electrical insulation markets in India.
Product Recommended
Based on the customer's application, Chengrui recommended 2753 silicone coated fiberglass sleeving.
This product is made from non-alkali braided fiberglass sleeving coated with silicone resin.
| Item | Confirmed Product Information |
| Product Name | Silicone Coated Fiberglass Sleeving |

The customer selected several commonly used inner diameters instead of only one size. This helped them supply different motor repair workshops and wiring applications.
Sample Confirmation Before Order
Before placing a bulk order, the customer requested samples.
They wanted to check the material by hand because many local buyers care about the practical installation experience, not only the technical datasheet.
The customer checked:
inner diameter accuracy
coating uniformity
surface smoothness
flexibility
color appearance
cutting edge condition
wire insertion performance
packing condition
After receiving the samples, the customer confirmed that the sleeving was suitable for their application.
The most important feedback was that the sleeve could be inserted over motor leads smoothly, and the coating surface looked clean enough for resale.
Order Arrangement
The first order was arranged as a mixed-size order.
The customer did not want a very large quantity of one single diameter. They needed several sizes in one shipment to test demand in their local market.
Chengrui prepared the goods according to the confirmed size list and packing requirements.
The order included:
multiple inner diameters
several common colors
2.5kV and 4kV voltage grade options
carton export packing
clear product labels
mixed-size shipment
This type of order is common for insulation material distributors. They need enough size options to serve different end users, but they also need to control stock risk at the beginning.
Customer Feedback
The customer's feedback was practical and specific.
They did not say anything exaggerated. Their comments mainly focused on three points.
1. Coating Surface Was Clean
The customer said the sleeving surface was cleaner than some local low-cost products they had seen before.
For resale customers, appearance matters because uneven coating may make buyers worry about quality.
2. Diameter Was Suitable for Installation
The inner diameter matched the sample requirement, and the sleeve could be installed smoothly over the lead wires.
For motor repair shops, this is important because sleeving that is too tight wastes time during assembly.
3. Mixed Sizes Helped Local Sales
The customer appreciated that Chengrui could supply mixed sizes and colors in one order.
This helped them test the Indian market without stocking too much of one single size.
