Applications
Ourstanding electrical insulation and waterproofing performance, ideal to apply in the electrical power and communication industries.
For cable insulation, busbar insulation, base station insulation and transformer insulation.
To wrap HB525W around conductors for localized insulation.
Waterproof sealing and insulation protection of overhead line clamps.
Waterproof sealing and insulation protection of exposed metal parts at electrical connection points.
Repairing damaged cable terminals.
Insulation sealing and protection of exposed metal parts at busbar connection points in switchgear cabinets.
Application Case 1: 10KV Overhead Bare Conductor Insulation Treatment
When 10KV overhead bare conductors are too close to buildings, compromising the required safety distance, HB525W is wrapped around the section of the conductor near the building to provide insulation protection. This ensures safety by insulating the conductor and mitigating the risks associated with close proximity to residential or commercial structures.
Application Case 2: Insulation Sealing of Exposed Electrical Connection Points
The overhead wire is connected to the switch or transformer on outdoor column through the jumper, the connection point exposed in the air which easy to cause safety hazards after water vapor entered. For overhead insulated wires that connect to outdoor poles, switches, or transformers through jumper wires, the connection points are often exposed to the air, making them susceptible to moisture ingress, which can create safety hazards. The overhead wire is connected to the switch or transformer on outdoor column through the jumper,the connection point exposed in the air which easy to cause safety hazards after water vapor entered.For overhead insulated wires that connect to outdoor poles,switches,or transformers through jumper wires,the connection points are often exposed to the air,making them susceptible to moisture ingress,which can create safety hazards.
These points usually have irregular shapes,but HB525W can adhere effectively to these irregular metal connection points,ensuring a secure and reliable waterproof seal.
Superior UV resistance property,allowing for long-term use in outdoor environments.After curing,it provides mechanical protection,making it durable and easy to apply in various outdoor conditions.

Application Case 3: Insulation and Sealing Protection for Overhead Line Clamps
Line clamps,which act as conductors for electrical current and connect power fittings are more prone to moisture ingress than conductors due to their unique structure and location.Moisture accumulation inside the clamps can cause significant hazards.
There are many types of overhead conductor clamps,such as tension clamps,wedge clamps,parallel groove clamps and H-type clamps,most of which have irregular shapes.In its uncured state,HB525W is very soft and conformable,making it easy to adhere to these irregularly shaped clamps.Additionally,HB525W adheres well to metal surfaces,ensuring a secure fit.
With excellent UV resistance property,HB525W is suitable for long-term outdoor use.Once cured,it provides mechanical protection,further enhancing its durability in outdoor environments.
Application Case 4: Top Insulation of Support Insulator
The exposed wires on both sides of the support insulators on 10KV overhead line towers are prone to contact by birds or objects such as metal wires carried by birds, which can cause line tripping.
The HB525W is mainly used for insulation protection within a certain range on both sides of the support insulators to prevent short circuits and tripping caused by bird contact.
Application Case 5: Sealing Cable Entry Holes at the Bottom of Switchgear and Distribution Boxe
Sealing the cable entry and exit holes in distribution boxes is challenging. Over time, regular sealing materials will getting crack, moisture or insects/tiny animals enter the box. Additionally, these holes often contain multiple cables, and improper application or insufficient adhesion will cause the seal to fail.
HB525W sealing perform excellent conformability and strong adhesion to metal,it can tightly adhere to cables,regardless of their shape or arrangement and Ensures a secure seal that won’t fall off,allowing for long-term use.
Application Case 6: Insulation Repair for Insulated Wires
The exposed metal conductor should be repaired effectively before removing the hardware such as the cable clamp or changing the cable terminal jumper.During maintenance,the insulation of the wire should be peeled for temporary grounding and other reasons,and the insulation should also be repaired in time.
HB525W is used for insulation recovery of wires.
Application Case 7: Insulation Sealing for Exposed Metal Parts Inside Switchgear
Due to the moisture entering the cabinet,the switch cabinet may cause moisture to the primary or secondary equipment,resulting in corrosion,poor contact,short circuit and other problems,affecting the insulation performance of the cabinet.
The exposed part of the metal is covered with HB525W so that it does not come into direct contact with the air,thus reducing the degree of corrosion.
When repair,remove HB525W,after repair, re-wrap HB525W, which can minimize the corrosion of copper bars and epoxy parts.
Application Case 8: Localized Repair of Damaged Cable Terminals
The crack at the top of the cable terminal can be repaired with HB525W to delay the cracking speed and prevent rain from entering the crack, which will affect the terminal life. When the top of a cable terminal cracks, HB525W can be used to repair the damaged area. This helps to slow down the cracking process and prevents rainwater from entering the cracks, which could reduce the terminal''s lifespan.
